The height of a cone is decreasing at a constant rate of 9 feet per second. The volume remains a constant 689 cubic feet. At the instant when the height of the cone is 88 feet, what is the rate of change of the radius? The volume of a cone can be found with the equation V=\frac{1}{3}\pi r^2 h. V= 31​ πr 2 h. Round your answer to three decimal places.
