Dec 21, 2020 · Even though we introduced it first, the Disk Method is just a special case of the Washer Method with an inside radius of r (x)=0. Example \PageIndex {4}: Finding volume with the Washer Method Find the volume of the solid formed by rotating the region bounded by y=x^2-2x+2 and y=2x-1 about the x …

### difference betweendisc method washer methodand shell

Jul 19, 2020 · Re: Difference between disc method, washer method and shell meth. Murray 12 Dec 2015, 05:22. Hi Shaikshavali. The disc method for finding a volume of a solid of revolution is what we use if we rotate a single curve around the x- (or y-) axis. If we do that and take slices perpendicular to the axis, we will produce a series of discs (like my watermelon example on this page:)

### volume of revolution:disk 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

### when to use washer, shell or disk| physics forums

Feb 21, 2005 · When using washer, the segment is rotating perpendicular to the axis of rotation. This yields the integral where you have integral [(pi R^2)-(pi r^2)], where R is the radius of the larger disk or washer, and little r is (you guessed it!) the radius of the smaller or inner disk. Happy integrating!

You can always use either, the difference is that the washer method takes the cross-section of your final shape, then rotates it, while the disk method subtracts the entire volume of the shape enclosed by g (x) from the shape enclosed by f (x)
