8-57.
Suppose the shape in problem 8-55 was revolved around the line
Like problem 8-55, the rotating radius will be horizontal (because the axis of rotation is vertical). Consequently, the bounds of integration will be y-values: from
Unlike problem 8-55, there will be a cylindrical hole in the center of this 3D figure. This hole has a radius of
Unlike problem 8-55, the outer function is no longer
