The circumference of the circle is a measure of its ''length'' and so the circumference of a circle with diameter 2 inches will be twice the circumference of a circle with diameter 1 inch. WebCircumference is equal to 2 pi r. And in this case, r is equal to 6. So it's equal to 2 pi times 6, which is going to be equal to 12pi. So that's straightforward, area 36pi, we leverage pi r squared to figure out that the radius was 6, and then from that we were able to figure out that the circumference was 12pi.
