Asked by robby
mistyped before. A sphere has a volume of 500/3 pi cubic centimeters. What is the total surface area in square centimeters, of the sphere? The correct answer is 100pi, but I have no idea why. I need to see it worked out from start to finish :(

V = (4/3)πr^3
(500/3)π = (4/3)πr^3
r^3 = 125
r = 5
Surface area of sphere = 4πr^2
= 4π(5^2) = 100π
(500/3)π = (4/3)πr^3
r^3 = 125
r = 5
Surface area of sphere = 4πr^2
= 4π(5^2) = 100π
