Question

What is the volume of a sphere with a surface area of 25pi yd^2?

Answer 1

SA of a sphere is 4pi r^2. through integration, volume is 4/3 pi r^3.

Answer 2

does that help you get started?

Answer 3

ok, maybe not. ok, so the radius^2 is 25/4. if you need help finding that, I can help you, but lets move on. the root of that it 5/2, which is your radius. so, the volume is 4/3 times pi times (5/2)^3

Answer 4

(4/3)(125/8)pi = (125/6)pi yd^2, unless that reduces
