36. A faucet is filling a hemispherical basin of diameter 60 cm
with water at a rate of 2 L/min. Find the rate at which the
water is rising in the basin when it is half full. [Use the
following facts: 1 L is 1000 cm³. The volume of the portion
of a sphere with radius r from the bottom to a height h is
V = π (rh²h³), as we will show in Chapter 5.]

37. Boyle's Law states that when a sample of gas is compressed
at a constant temperature, the pressure P and volume V
satisfy the equation PV = C, where C is a constant. Sup-
pose that at a certain instant the volume is 600 cm³, the
pressure is 150 kPa, and the pressure is increasing at a rate
of 20 kPa/min. At what rate is the volume decreasing at this
