A propane gas tank consists of a cylinder with a hemisphere at each end. Find the volume of the tank if the overall length is 20 feet and the diameter of the cylinder is 6 feet (round to an exact number) (see figure in the website below).

You have the diameter of the cylinder, and thus the radius of the hemispheres. Find the volume of the sphere formed by the two hemispheres, and add that to the cylinder's volume.
