The shell method will yield a direct answer, but the disk method requires us to figure out all the corresponding functions. x x -axis. (The shell method corresponds to using the red rectangles, while the disk method corresponds to using the blue rectangles minus the yellow rectangles.) x = 0 , y = 2 x = 0,y = 2. When x = 1, y = 1, 3 x = 1,y = 1,3.
