The radius of a cone is decreasing at a constant rate of 7 feet per minute, and the volume is decreasing at a rate of 128 cubic feet per minute. At the instant when the height of the cone is 11 feet and the volume is 11 cubic feet, what is the rate of change of the height? The volume of a cone can be found with the equation V=13πr2h.V=31​πr2h.Round your answer to three decimal places.
