25. ..s) Two circles, each of radius r, have their centers located at (0,2) and (0,3). Each is used to create a volume of revolution that is a torus when the circle is rotated 360° around the x axis. Using a concept from this course, prove mathematically that the ratio of the volumes of the two toruses is 1.5.
