17. Find the volume of each solid obtained by rotating the bounded region around the given axis using the shell method. Remember with shell method the general equation is 2 rh dy for a x axis rotation b L and 2 b L rh dx for a y axis rotation where r is the radius (usually x if it's dx and y if it's dy) and h is the height of the rectangle. a. Region bounded by y = 2x x2 and the x axis. Rotated about the y-axis.
