Gravel is being dumped from a conveyor belt at a rate of 50 cubic feet per minute. It forms a pile in the shape of a right circular cone whose base diameter and height are always equal. How fast is the height of the pile increasing when the pile is 16 feet high? Recall that the volume of a right circular cone with heighth and radius of the base r is given by 1 V = = πr²h 3 ft min A rotating light is located 14 feet from a wall. The light completes one rotation every 4 seconds. Find the rate at which the light projected onto the wall is moving along the wall when the light's angle is 5 degrees from perpendicular to the wall. wall V light feet per second At noon, ship A is 40 nautical miles due west of ship B. Ship A is sailing west at 22 knots and ship B is sailing north at 24 knots. How fast (in knots) is the distance between the ships changing at 6 PM?
