I have a math question and I don't know what to do.
"Find the circumference of a sphere with a surface area of 60Pi in^2"
So should I plug the surface area into the formula and try to find the radius? I know it's probably a pretty obvious answer but for some reason I can't seem to grasp what to do. Please help me! Thanks!

SA= 4*pi*r^2 = 60pi therefore r= sqrt(15)
Circumference= pi*2*r where 2r=diameter
...= 2pi*sqrt(15)
