An inverted cone has a height of 15 mm and a radius of 16mm. The volume of the inverted cone is decreasing a rate of 534 cubic mm per second, with the height begin held constant. What is the rate of change of the radius, in mm per second, when the radius is 6 mm?

Round your answer to the nearest hundreth. (Do not include any units in your answer

Remember that the volume of a cone is$=V=\frac{1}{3}\pi {r}^{2}h$
