disk vs washer method

Such a disk looks like a “washer” and so the method that employs these disks for finding the volume of the solid of revolution is referred to as the Washer Method. The following example demonstrates how to find a volume that is created in this fashion

    Feb 21, 2005 · Depending on how the solid is described, you'll sometimes find the shell method easier to integrate than the washer method and vice versa. If you set up the integral one way and you're finding it hard to evaluate, try using the other method. Try doing the same problems using both methods, it's a good way to get a feel for when one is preferable

    Aug 28, 2015 · The disk method is typically easier when evaluating revolutions around the x-axis, whereas the shell method is easier for revolutions around the y-axis---especially for which the final solid will have a hole in it (hence shell). The disk method is: V = piint_a^b (r(x))^2dx The shell method is: V = 2piint_a^b xf(x)dx Another main difference is the mentality going into each of these
