Where r is the radius and h is the height.
Volume of the cone A:

Volume of the cone B:
If the height of the cone B and the height of the cone A are the same , but the radius of the cone B is doubled, then its radius is:

Then:

Divide
by
:

Therefore: When the radius is doubled, the resulting volume is 4 times that of the original cone.
