Find the volume of the cylinder: Use 3.14 for pi.

28ft

14ft

The formula for the volume of a cylinder is V = πr^2h, where r is the radius and h is the height.

Given that the radius is 14ft and the height is 28ft:
V = 3.14 * 14^2 * 28
V = 3.14 * 196 * 28
V = 5921.12 cubic feet

Therefore, the volume of the cylinder is 5921.12 cubic feet.
