 CD's Pi Project  This is a section on the number Pi. If you want to know a lot about Pi, this is the webpage for you. By Pi, i'm not saying the pie with pecons and nuts. I'm talking about the number Pi. It is a decimal that never ends. Enjoy!

- **What is Pi?** Pi is the ratio of the circumference of a circle to its diameter.

- **What language does Pi come from**? Pi came from the Greek language.

- **What kind of number is Pi?** Pi is a non-repeating, non-terminating decimal. That means it never ends and never repeats.

- **This is a brief summary of Pi:** Pi is really old. The Egyptians and the Babylonions knew the ratio Pi. They did not know nearly as much of its value as we do today. Then they figured out that Pi is just a tiny bit bigger than 3.

- ​**What formulas use Pi?** One formula that uses Pi is Pi times the diameter of any circle. It equals the circumference of any circle. Here are some other formulas: Circumference=2 × Pi × The radius of a circle. Area of a circle=Pi × //r²//. Surface Area of a cylinder=2Pi//rh//+ //2//Pi//r²// Volume of a cylinder=Pi//r²h// V of a cone=1/3Pi//r²h//

- **How do you calculate Pi?** If you measure the diameter and circumference of a circle, then divide the circumference by the diameter, well if you calculate it right, you'd get Pi.

- **How many digits has it been calculated to?** Pi has been calculated to 1.24 TRILLION!

- **Can I find cool digits (such as my birthday) in Pi?** Actually, yes I can. My birthday (7/29/98) shows up in the106,513 place of Pi. The 3. is not counted. You can see where your birthday is in Pi at the link at the bottom.

PI looks like a big number, but really it is only just a tiny bit bigger than 3. Isn't that cool?
