Suppose we wanted to estimate the surface area with two frustums with .
Bounded region rotated about -axis.
Figure137.Plot of bounded region rotated about -axis. What is the surface area of the frustum formed by rotating the line segment from to about the -axis?
Figure138.Plot of bounded region rotated about the -axis. What is the surface area of the frustum formed by rotating the line segment from to about the -axis?
