What are some facts about the Orgin Of pi?
115785
The value of π has been known in some form since antiquity. As early as the 20th century BC, Babylonian mathematicians were using π=25/8, which is within 0.5% of the exact value.\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. 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.)

Pi is the ratio of circumference to diameter. The Indians, the Egyptians, the Greeks and the Babylonians all knew that the ratio of the circumference to the diameter of a circle is the same for all circles, and that it is slightly more than 3. The Indians and Greeks also knew that the area of a circle is πr^2. Archimedes showed that the volume of a sphere is (4/3)πr^3 and that the surface area of a sphere is 4πr^2. By finding perimeters of circumscribed and inscribed regular polygons, Archimedes found that π is between 3 + 10/71 and 3 + 1/7.  In 1761, Johann Heinrich Lambert showed that π is an irrational number by showing that it has a generalized continued fraction that does not terminate. In 1882, Ferdinand von Lindemann proved that π is a transcendental number. With the appearance of computers, a hunt on millions and billions of decimal places of π has started and is still ongoing.

My user name shows the formula. e to the i(pi) is equal to -1. It is known as the most beautiful formula, since e, i, and pi are not related much. \nThis formula links the three most important constants together.

Impossible to answer.  Pi is an irrational number meaning that the numbers after the decimal will continue until infinity.  While supercomputers can give the number to "upteen" decimal places, we can never know the last decimal place.

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

PI(π)= 3.14159 26535 89793 23846 26433 83279 50288 41971 69399 37510...\nIt is a Greek letter, and an irrational number. Some formulas it is used in include the formulas for area/perimeter of a circle, surface area of a sphere, and volume of a cylinder. Pi may be 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.

It is said that the area of a circle is Pi R square.  Pie are not square. Pie are round, cornbread are square.

One secret that pi is still holding from us is whether its digits are really random. Although it seems to be true, nobody has been able to prove it yet.

I don't know why 4 of the 8 answers so far say it's true. It's false.\nOne of them reversed the inequlity, and so gave the wrong answer.\ne=2.71828182845905\npi=3.14159265358979\n\ne^pi=23.1406926327793\npi^e=22.459157718361\n\ne^pi < pi^e is false\nChecking to 510 decimal places won't change the result.

Pi is the result of dividing the diameter of a circle by its circunference.

Since pi is an irrational, transcendental number, it cannot be "defined" by an integer division.\n\nIts definition is "the circumference of a circle divided by its diameter", conventionally denoted by the (lowercase Greek letter) π.\n\nIt's approximation is 3.14159265, and it is this "approximation" that is commonly represented as 22/7. But this is not the pi (π) itself.

Pi is not an infinite number however has infinite number of digits after the decimal point. (Please see the link for more information).

Pi is the ratio of the circumferance of a circle to its diameter.  The following equation is for the area of a circle:    A = pi*r^2\n\nThe Math Forum website has a very complete and east-to-understand explanation.

Ha!  I just happen to know pi to 60 decimal places off the top of my head.  \n3.141592653589793238462643383279502884197169399375105820974944

By definition, pi is the ratio of the circumference of a circle to its diameter. Pi is always the same number, no matter which circle you use to compute it. \nFor the sake of usefulness people often need to approximate pi. For many purposes you can use 3.14159, which is really pretty good, but if you want a better approximation you can use a computer to get it. Here's pi to many more digits: 3.14159265358979323846.
