WebCircumference: The length of the great circle of the sphere is called its circumference. In the figure given below, the boundary of the dotted circle or the cross-section of the sphere containing its center is known as its circumference. ... In terms of diameter, the surface area of a sphere is given as S = 4π(d/2) 2, where d is the diameter ... WebSo the circumference is equal to 2 pi r. Circumference 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 ...
