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 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. (a) At time t = k, at what rate is the area of the circular surface of the dough increasing with respect to time? Show the computations that lead to your answer. Indicate units of measure. Please respond on separate paper, following directions from your teacher. (b) At time t = k, at what rate is the height of the dough decreasing with respect to time? Show the computations that lead to your answer. Indicate units of measure. (The volume V of a cylinder with radius r and height h is given by V = ar² h.) %3D U Please respond on separate paper, following directions from your teacher. c) Write an expression for the rate of change of the height of the dough with respect to the radius of he dough in terms of height h and radius r.
