What is a circumference?
Circumference is the distance of the outside of the circle. It's basically the perimeter of the circle.
-the outside circle indicates the circumference
The formula for circumference is 2pr(2 x p x r).
e.g.
The radius is 3m, what is the circumference?
A=2pr
A=2 x 3.14 x 3
A=6.28 x 3
A=18.84m
