The value of pi is a constant which equals the circumference of a perfect circle divided by its diameter. It is a transcendental number, meaning that the number of decimals is infinite, yet all the numbers are defined. Pi holds a certain mystique to it, as it shows up in all kinds of math equations.\n\nYou may recognize its value as 3.1415926535897932384...\n\nPi was simply the Greek symbol chosen to represent this value.

From Wiki:"The use of the Greek letter π for this constant is derived from Greek words like περιφέρεια (for periphery) and περίμετρον (for perimeter) starting with this letter.\nThe name of the Greek letter π is pi, and this spelling is used in typographical contexts where the Greek letter is not available or where its usage could be problematic. When referring to this constant, the symbol π is always pronounced like "pie" in English, the conventional English pronunciation of the letter."\n\nFrom Online Etymology Dictionary:\nPi: "1841, used in L. 1748 by Swiss mathematician Leonhart Euler (1707-83), from Gk. letter pi (from Heb., lit. "little mouth") as an abbreviation of Gk. periphereia "periphery." "\n\nMy initial guess was that it was derived from Latin, since many of our words have Latin origins.  But, apparently it is Greek in origin and is used because the Greek symbol Pi means perimeter thus corresponding to circles.

It's spelled "pi" and it's used in trigonometry because it's how you measure a circle in radians. Radians is a better way to measure angles - pi is equivalent to 180 degrees, and 2pi is equivalent to 360 degrees.

I think it means quite a bit, but we haven't discovered the true meaning of it. e & pi both come up a lot in number theory & other disciplines.\n\nI think it may have to do with an oversight in our current decimal number system.

It's a food, typically with a crust and some good stuff in the middle.\n\nIf you mean pi, then it's the ratio of the circumference of a circle to its diameter.  Its value is approximately 3.14.

Lots of numbers show up frequently, especially when you are looking for them.  This is a relatively common phenomenon that is experienced by quite a lot of people.\n\n1024 is a very commonly occuring number because it is 2^10\n1023 = 2^10 - 1\n\nThere is a movie called Pi, it is about a guy who becomes obsessed looking for a particular "216" number as it is called.  After I watched the movie, I've noticed that I see the number 216 quite frequently.

everything has a sqare root , archimedes was said to be the first to discover the square root to everything by using the simplest mathmaticial soloution even used today wihch goes 1,2,3,5,8,13,21 and on and on and on forever just like the universe and i am no "string theorist" either ... as for symmetry well thats another story.... pie is what im sure you know as 3.14 and is used to measure any size of circles and is used to proove that the universe is infinate because pie is infinate, take a look at this cut and paste and then veiw the proof on the link i have provided about it.... o.k here it is... \n\nFrom the definition, π can be found by taking a circle (any circle at all) and dividing the length of its circumference3 by the length of its diameter4. This will give you a value close to the number stated below, depending on how accurate your measurements are.\n\nWhat Exactly is the Value of π?\n\nπ, to 2,000 decimal places, is:\n\n3.1415926535897932384626433832795028841971693993751058209749445\n923078164062862089986280348253421170679821480865132823066470938\n446095505822317253594081284811174502841027019385211055596446229\n489549303819644288109756659334461284756482337867831652712019091\n456485669234603486104543266482133936072602491412737245870066063\n155881748815209209628292540917153643678925903600113305305488204\n665213841469519415116094330572703657595919530921861173819326117\n931051185480744623799627495673518857527248912279381830119491298\n336733624406566430860213949463952247371907021798609437027705392\n171762931767523846748184676694051320005681271452635608277857713\n427577896091736371787214684409012249534301465495853710507922796\n892589235420199561121290219608640344181598136297747713099605187\n072113499999983729780499510597317328160963185950244594553469083\n026425223082533446850352619311881710100031378387528865875332083\n814206171776691473035982534904287554687311595628638823537875937\n519577818577805321712268066130019278766111959092164201989380952\n572010654858632788659361533818279682303019520353018529689957736\n225994138912497217752834791315155748572424541506959508295331168\n617278558890750983817546374649393192550604009277016711390098488\n240128583616035637076601047101819429555961989467678374494482553\n797747268471040475346462080466842590694912933136770289891521047\n521620569660240580381501935112533824300355876402474964732639141\n992726042699227967823547816360093417216412199245863150302861829\n745557067498385054945885869269956909272107975093029553211653449\n872027559602364806654991198818347977535663698074265425278625518\n184175746728909777727938000816470600161452491921732172147723501\n414419735685481613611573525521334757418494684385233239073941433\n345477624168625189835694855620992192221842725502542568876717904\n946016534668049886272327917860857843838279679766814541009538837\n863609506800642251252051173929848960841284886269456042419652850\n222106611863067442786220391949450471237137869609563643719172874\n677646575739624138908658326459958133904780275901\nOf course, that's not where it ends. π continues for an infinite number of decimal places, and there is no pattern to the order of the digits. Any pattern that you may think is emerging is just an illusion, and will quickly disappear to be replaced by another 'pattern'. For ease of mathematical calculations, π is usually reduced to 3.142, or 3.14159 for a more accurate result.

In Euclidean plane geometry, π(Pi) is defined either as the ratio of a circle's circumference to its diameter, or as the ratio of a circle's area to the area of a square whose side is the radius. π may be defined in many other ways, for example as the smallest positive x for which sin(x) = 0. See other formulas below. All these definitions are equivalent.\n\nArea of Circle = Pi.(Radius)^2\nPerimeter of Circle (Circumference)=2.Pi.Radius.\nYes .. it has someting to do with Statistics :\n\nIn probability and statistics, there are many distributions whose formulæ contain π, including:\n\nprobability density function (pdf) for the normal distribution with mean μ and standard deviation σ : \nhttp://en.wikipedia.org/wiki/Pi

The value of π has been known in some form since antiquity. As early as the 19th century BC, Babylonian mathematicians were using π=25/8, which is within 0.5% of the exact value.\n\nThe Egyptian scribe Ahmes wrote the oldest known text to give an approximate value for π, citing a Middle Kingdom papyrus, corresponding to a value of 256 divided by 81 or 3.160.\n\nIt is sometimes claimed that the Bible states that π=3, based on a passage in 1 Kings 7:23 giving measurements for a round basin as having a 10 cubit diameter and a 30 cubit circumference. Rabbi Nehemiah explained this by the diameter being from outside to outside while the circumference was the inner brim; but it may suffice that the measurements are given in round numbers. Also, the basin may not have been exactly circular.\n\nThe Chinese mathematician Liu Hui computed π to 3.141014 (good to three decimal places) in AD 263 and suggested that 3.14 was a good approximation.\n\nThe Indian mathematician and astronomer Aryabhata in the 5th century gave the approximation π = 62832/20000 = 3.1416, correct when rounded off to four decimal places.\n\nThe Chinese mathematician and astronomer Zu Chongzhi computed π to be between 3.1415926 and 3.1415927 and gave two approximations of π, 355/113 and 22/7, in the 5th century.\n\nThe Indian mathematician and astronomer Madhava of Sangamagrama in the 14th century computed the value of π after tranforming the power series expansion of π/4 into the form\n\nπ = √12(1 - 1/(33) + 1/(532) - 1/(733) + ... \nand using the first 21 terms of this series to compute a rational approximation of π correct to 11 decimal places as 3.14159265359. By adding a remainder term to the original power series of π/4, he was able to compute π to an accuracy of 13 decimal places.\n\nThe Persian Muslim mathematician and astronomer Ghyath ad-din Jamshid Kashani (1350-1439) correctly computed π to 9 digits in the base of 60, which is equivalent to 16 decimal digits as:\n\n2 π = 6.2831853071795865 \nThe German mathematician Ludolph van Ceulen in 1615 computed the first 32 decimal places of π. He was so proud of this accomplishment that he had them inscribed on his tombstone.\n\nIn 1789, the Slovene mathematician Jurij Vega improved John Machin's formula from 1706 and calculated the first 140 decimal places for π of which the first 126 were correct [1] and held the world record for 52 years until 1841, when William Rutherford calculated 208 decimal places of which the first 152 were correct.\n\nThe English amateur mathematician William Shanks, a man of independent means, spent over 20 years calculating π to 707 decimal places (accomplished in 1873). In 1944, D. F. Ferguson found (with the aid of a mechanical desk calculator) that Shanks had made a mistake in the 528th decimal place, and that all succeeding digits were fallacious.

Actually, there are more numbers that do not repeat than numbers that repeat. \n\nAnd pi is one of those numbers that does not repeat.

pi is a perimeter around a circle, it's 3.14 because if we wrote the actual number of pi it wouldn't stop

You are correct about the conversion; however, the use of 'pi' is indicative of radians.

Pi is never mentioned in the Bible; it is implied!   We (and let me repeat, we) deduce that pi is the 30 cubits around by 10 cubits brim to brim simplifies to just 3.    \n\nThe translations of the Bible over the span of mankind have changed the wordings and even the meanings of some verses.\nSince the original author(s) of Kings was inspired by God they would have spent their minds on faith and poetic emotion rather than intense technical information such as describing decimals.  The information for someone building or doing basic construction can and easily get by with just an approximate value of 3

The common symbol often used for pi, is the lowercase Greek letter P.  Euler popularized William Jones use of the symbol, which Jones first put the symbol to the number in 1706. Other mathmaticians before that had applied the symbol to related ratios.

The Greek letter pi is a constant approximately equal to 3.1415. It is irrational, meaning that it has been proven that it's digits continue forever without repeating, and that it cannot be written as a fraction.\n\nThe definition of pi is the ratio of a circle's diameter to it's circumference, but it has the curious property of popping up all over the place in other forms of math too.
