Question

If a sphere's volume is doubled, what is the corresponding change in its radius? A. The radius is increased to 20 times the original size. B. The radius is increased to 4 times the original size. C. The radius is increased to 2 times the original size. D. The radius is increased to 8 times the original size

Answer 1

The radius is increased by 1.2599 times the original size.

Explanation:

The volume is 3 dimensional whereas the radius is one dimensional.

Therefore the factor for the radius will be the cube root of the factor for the volume.

So the radius is increased by 1.2599.
