what really is pi? 3.1444

Hi Rachel,

If you have any circle, measure its circumference and diamater exactly, and divide the circumference by the diameter, the answer is always the same. It doesn't matter how large or small the circle, the circumference divided by the diameter is the number we call pi. Pi is approximately 3.1416 and hence

circumference/diameter = 3.1416 or equivalently circumference = 3.1416 x diameter.

There is much more information on pi on The p Pages
