How To Calculate

Use the formula.

The circumference of a circle is found with the formula C= π*d = 2*π*r. Thus pi equals a circle's circumference divided by its diameter. Plug your numbers into a calculator: the result should be roughly 3.14. Don’t draw a crappy circle like this one, if your circle is poorly drawn, the result WONT be 3.14159264358979323846263!!

I did it once, and got 3.141593746484837, NOT PI. Use a good circle!! The Pi gods DEMAND IT!!!
