Ruben put an empty cup underneath a leaking faucet. After 1-1/2 hours, Ruben had collected 1/4 cup. What is the rate, in cups per hour, at which the water is leaking from the faucet?

answer rather than having to add and subtract the measurements of the semi-circle, notice that the semicircle to the left of ad is actually identical in area to the blank semicircle-shaped space to the left of bc. so if we transferred the red semicircle into the blank space, we would end up with a square of side length 24 cm. the area of a square is s^2 = 24^2 = 676 cm^2.
