Why does pi start with 3 and not any other number?

Pi is defined as the ratio between the circumference of a circle, and the distance across a circle (the diameter).\n\nLet's start with a hexagon.  Notice how you can fit a regular hexagon inside a circle.  Look at the "radius" of a hexagon (distance to a vertex).  Let's call that r.  Double that is 2r.  And the distance around the hexagon is 6r.  So the ratio of perimeter to "diameter" is exactly 3.\n\nNow if you try polygons with larger numbers of sides (better approximating a circle), the number gets bigger.  Octagons have a ratio of 3.0616.  A decagon will have a ratio of a little more than that and a dodecagon more than that.  But it starts approaching a limit.  Certainly never more than 4... actually never more than pi, until you get all the way to an infinite sided polygon which would be a circle.\n\nThe ratio will approach pi (3.141592653589...) as a limit.  A hexagon starts at 3.0, other shapes add more to the decimal portion, but never make it exceed pi.  So it will never jump to 4 or go below 3.\n\nSo that is why pi starts with 3.

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.

I just did my senior research paper on pi in hexadecimal looking for patterns and also used an algorithm to find the nth hexadecimal digit without calculating the prior n-1 digits.  Yes, it was a lot of hours.

thats silly\na factor of a number is a number that can be called a divisor of that original number...pi is irrational...therefore it has no factors\n\nif your looking for the 20th digit of pi, its 4\n\nhope this helps\nmatttlocke

Pi is a constant, just like 2 or 3.

Irrational numbers don't have patterns, either.\n\nYou could take pi or e or sqrt(2) out to a hundered digits and stat test it.\n\nI just looked at sqrt(2), sqrt(3), and e.  I couldn't see any pattern to occurances.\n\nAlso, I can't think of any reason there would be more of some number than another.  For years, sqrt(prime) has been used as a source of random numbers.

They call ZERO an even number, who are they that mention like this?\n\nActually, odd numbers are start with 1, then 3, 5, etc., even numbers are start with 2, then 4, 6, etc.\n\nIf you check at the numbers system, then you can understand what meant by odd number, even number, negative number, natural number, whole number and others. \n\nSo, here the point is, ZERO actually is not a even number (the smaller even number start with 2), then there was no reason to tell you that why can call it an even number.

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.

All primes (ignoring 2) are odd.\n\nDivide odd numbers into 3 groups: those of the form 6n - 1, those of the form 6n + 1, and those of the form 6n + 3.\n\nIgnoring 3 itself, all primes are of the form 6n + 1 or 6n - 1, as all numbers of the form 6n + 3 or 6n - 3 are divisible by 3 and not prime. \n\nYour proposition follows from that fact.

Over the ages of time, Pi has had various names in numbers and symbols since Pi cannot be shown in an exact number of form. People had various variations of what Pi actually was, but to none of them came the answer we still strive to find today.\n\nPi was first mentioned in Egypt. The first reference to Pi was in a Middle Kingdom papyrus scroll written sometime around 1650 BC. This scroll of significance was written by Ahmes. He states at the end of this scroll, which was titled, "The Entrance into Knowledge of All Existing Things," that the area of a circle is found using a rough sort of Pi. Ahmes had no idea how famous Pi would become and the mysteries regarding it.\n\nDuring the time of 200 BC, Archimedes of Syracuse discovered the value of Pi was about 3.14. The Greeks never used decimals, so they wrote it as a fraction back then. Archimedes discovered 3.14 by constructing a polygon with 96 sides and inscribing a circle in it. Although this was an historic discovery, it wasn’t the actual value of Pi. After this discovery, little progress and research was carried out dealing with Pi until the 17th century. Pi was given the title of the Ludolphian number, after a famous German mathematician named Ludolph van Ceulen.\n\nWilliam Jones also made history with Pi by becoming the first person who put the famous label of p on Pi in 1706. The use of p as a symbol of Pi by this English mathematician is still used to this very day and is known as the signature symbol for Pi.

Pi is approximately 3.14159.  It is the never ending number that results from dividing the circumference of a circle by it's diameter.

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.
