Cylindrical shell vs washer method

Websolid of revolution are the (cross sectional) disk method and the (layers) of shell method of integration. To apply these methods, it is easiest to: 1. Draw the plane region in question; 2. Identify the area that is to be revolved about the axis of revolution; 3. Determine the volume of either a disk-shaped slice or a cylindrical shell of the ... As we know the washer method and shell method both apply in the calculations. But the uses of both methods are vital and beneficial method of integration. Sometimes, it is best to use the washer method in case of finding volume of solid revolutions and sometimes the shell method works more … See more Suppose that we have a region R, bounded between the curves y=f(x) and y=g(x) from x = a to x = b as shown in a figure. If we take this region and revolve it around the y axis, we obtain the following solid of revolution … See more For understanding the washer method, we will recall the washer method about the y-axis.
