Sand is pouring from a pipe at the rate of 80 ft/s. The falling sand forms a conical pile on the ground. The height of the cone is always one-half the radius of its base. How fast is the height of the cone increasing when the pile is 20 feet high? (Recall: V = r² h) O 45 ft/sec O 1/45 ft/sec O 1/20 ft/sec O 20 ft/sec 1/20 ft/sec

Question
Sand is pouring from a pipe at the rate of 807 ft3/s. The falling sand forms a conical pile on the ground. The height of the cone is always one-half the radius of its base. How fast is the height of the cone increasing when the pile is 20 feet high? (Recall: V = ²h) 45 ft/sec O 1/45 ft/sec 1/20 ft/sec O 20 ft/sec O 1/30 ft/sec
