How do I solve this question: A constant volume of pizza dough is formed into a cylinder with a relatively small height and large radius. The dough is spun and tossed into the air in such a way that the height of the dough decreases as the radius increases but it retains its cylindrical shape. At time t=k, the height of the dough is 1/3 inch, the radius of the dough is 12 inches, and the radius of the dough is increasing at a rate of 2 inches per minute. At time t=k, at what rate is the height of the dough decreasing with respect to time. Indicate units of measure.
