Minimum Volume The function y = 4 − ( x 2 / 4 ) on the interval [0,4] is revolved about the line y = b (see figure). (a) Find the volume of the resulting solid as a function of b . (b) Use a graphing utility to graph the function in part (a), and use the graph to approximate the value of b that minimizes the volume of the solid. (c) Use calculus to find the value of b that minimizes the volume of the solid, and compare the result with the answer to part (b).
