What is circumfrence and how do you find it?

Answer 1

The circumfrence is like a perimeter. It is the area around a circle. You can find the circumfrence of a circle by using this formula. Pi x R2 or Pi times the radius squared.

Answer 2

C=π⋅2⋅r

The circle has a radius of 8 in.

Therefore:

C=π⋅2⋅8

and,

C=16π in
