Question 87997: The volume of a right circular cone of radius r and height r is given by V= pi/3 x r^3. How fast is the volume changing with respect to the changes in r when the radius is equal to 2 feet?

The volume of the right circular cone of radius r and height r is given by:
V+=+%281%2F3%29%28pi%29r%5E3
The change in volume with respect to r is:
dV%2Fdr+=+%28pi%29r%5E2 and when r = 2, then:
dV%2Fdr+=+4%28pi%29
