Question

Given two spheres, if the volume of the first sphere is 4/3 pie, and the volume of the second sphere is 36 pie, which is the relation of the second radius to the first? A.Squared B.Tripled C.Double

Answer 1

The answer is B because
The volume of the sphere is
V = (4/3)(pi)(r^3)
It is easy to see the radius of the small sphere is r = 1
The radius of the large sphere is
V = (4/3)(pi)(r^3) = 36 pi
r^3 = 36 (3/4) = 27
r = 3

We also can use the theorem
Lengths Areas Volumes
a/b (a/b)^2 (a/b)^3

However, in this specific problem, solving directly is easier.
