EXAMPLE 3.9.6
Gomer has noticed that when a garden hose is left exposed to the summer sunshine, the
water resting within the hose becomes heated. This inspires Gomer to construct a low-
tech solar water heater. He reasons that if he connects a sufficient length of hose and
leaves it in a sunny spot, this will provide an ample supply of hot water.
He estimates that the drum of his washing machine is a cylinder whose diameter is 17
inches and height is 10 inches. Based on that assumption, how many lineal feet of half-
inch diameter water hose would be required in order to hold enough water to fill the drum
of the washing machine?
