Minimum Volume
The function on the interval [0.4] is revolved about the line (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).
