Pi is the ratio of the circumfrence of a circle to its diameter. Pi is a Greek number and the Egyptians and the Babylonians knew about the existance of the ratio Pi. The Egyptians and the Babylonians figured out it was a little bigger than 3. The Babylonians had approximation of 3 1/8 [3.125]. The Egyptians had a harder and some what less nummber. Their approximation was 4* [8/9]^2.That's slightly less acurate. They all thought it was bigger than 3. Pi is a infinate decimal. Unlike numbers like 3,9.876 and 4.5. There are many formulas here are the ones I know.

 * **__What kind of number is Pi?__**
 * **__What formulas use Pi?__**
 * The circumfrence of a circle. C= 2**π**r or C= **π**d
 * The area of a circle. A=πr²

You divide the Circumfrence by the Diameter. Pi has so many numbers you can even find your birthday. The most digits people have found in Pi is more than 2 zillion numbers.Another interesting fact about Pie I mean Pi is computers and people are trying to find all the digits of Pi this very second.
