d=diameter
r=radias
r2=d
d=d
times the diamter by pi (3.14)
examaple:The radius of a pie is 2in. What is the circumfrence?
2 times 2 = 4in.
3.14 times 4=12.46sq.in.
this should answer you blah blah blah

C = 2 pi r
where pi is approximately 3.14 and r is the measure of your radius

Circumference = 2 * 3.14159 * radius
If you want to be super precise, you can use: 3.14159 26535 89793 23846 26433 83279 50288 41971 69399 37510 ...

pii r squared
pie are not square, pie are round, cornbread are square!
If you remember this funny you will never forget the formula
