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
