Water is poured into a container in the shape of a right circular cone with radius 4 feet and a height of 16 feet. Express the volume V of the water in the cone as a function of the height h of the water.

HINT GIVEN:

The volume V of a cone of radius r and height h is V = (1/3)(pi)(r^2)(h).

NOTE: Since the radius is 4 feet, does it mean the diameter of the cone is 8 feet?
