__Pi Page__ What is Pi?__** Pi is a decimal. It never ends or repeats. It is the ratio of the circumference of a circle to its diameter. It comes from Greek and is the sixteenth letter in the Greek alphabet. Pi is very old. The Egyptions an Babylonians knew about pi but they didn't know the value as much as us. They knew it was a little bigger then 3. Pi was chosen to represent the number 3.14... because the letter in Greek stands for perimeter. Pi is a nonreapeating, nonterminating number which means it never repeats or ends. **__Calculating Pi__** If a circle is one inch across the middle, then it is 3.14 inches around the outside. A professor calculated pi to 1.24 trillion digits. There are so many digits, you can find things like your birthday in them. [|learning about pi] [|pi song]
