If the diameter of a sphere is increased by 31% by what percentage of the original volume does the sphere increase to?
----------------
You can only spec the increased volume in terms of the original volume.
d --> d*1.31 (also r)
The formula for volume has an r^3 term --> it's a function of the cube of the radius.
Vol --> vol*1.31^3
= vol*2.248091
An increase of ~125%
