A barrel is shaped like an ellipsoid with equal pieces cut from the ends by planes perpendicular to the z-axis. The cross-sections perpendicular to the z-axis are circular. The barrel is 2h units high, its midsection radius is R, and its end radii are both r. Find a formula for the barrel's volume. Then check two things. First, suppose the sides of the barrel are straightened to turn the barrel into a cylinder of radius R and height 2h. Check to see if your formula gives the cylinder's volume. Second, suppose r=0 and h=R so the barrel is a sphere. Check to see if your formula give the sphere's volume.
