If the radius of a solid object increases 6 times, the volume of the object will increase how many times?

The volume will increase by 216 time of the original volume

Solution:

A sphere is a solid object.

Now, the volume of sphere is given by:

where

R = radius of the sphere

In the question the radius is increased 6 times, therefore, the new radius is:

R' = 6R

From the formula for the volume of sphere:

The volume of the sphere now becomes:

Thus the new volume will become 216 times of the original volume

the answer would most likely be c, because if it's a comical piece of information, it may likely not be true, if it's a site that allows anybody to edit the content, it could mean a five year old is typing the info, and if it's a tv show produced by a celeb, it may have a biased opinion.
