Question

Does anybody know this???Find the volume of a sphere if the surface area is 484pi cm^2 I calculated and the answer I got doesn't even match at all.

Answer 1

answer is 1774.7π cm^3
surface area of a sphere is 4πr^2 so you set up an equation
4πr^2=474π
divide by 4 to get 121 and the square root of 121 is ELEVEN. so the radius is 11
volume of a sphere is 4/3πr^3
volume is 1774.7π cm^3!!!
