Question 459755
Sphere B has 4 times the surface area of sphere A. How many times the volume of sphere A is the volume of sphere B?
I know the surface area formula for a sphere is 4(pi)(r)^2, however, when i did the problem, i was not sure whether the answer was 4pi

Given the formula for surface area and ratio of surface area of b to a is 4,
the radius of sphere B is 2x that of sphere A.

Since volume is expressed in r^3, volume of sphere B is 8 times that of sphere A
(2^3 = 8)
