< Question 5 of 10 The conical watering pail with height 0.45 m and radius 0.15 m has a grid of holes. Water flows out through the holes at a rate of kA m /min, where k is a constant and is the surface area of the part of the cone in contact with the water. This surface area is at which the water level changes at h = 0.18 m, assuming A = and the volume is V = IJtr2h. Calculate the rate dt that k = 0.26 m/min. 0.15 m 0.45 m (Give your answer to two decimal places.)
