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

H: 28ft
R:14ft

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

V = 3.14 * 14^2 * 28
V = 3.14 * 196 * 28
V = 3.14 * 5488
V = 17220.32 cubic feet

Therefore, the volume of the cylinder is 17220.32 cubic feet.
