Math Problem Statement
A fuel oil tank is an upright cylinder, buried so that its circular top is 8 feet beneath ground level. The tank has a radius of 7 feet and is 21 feet high, although the current oil level is only 17 feet deep. Calculate the work required to pump all of the oil to the surface. Oil weighs 50lb/ft^3.
