Solids of Revolution Question (Method of Cylinders vs Disc/Washers)

WebApr 13, 2024 · The Disk and Washer method is a calculus approach used to calculate the volume of a three-dimensional object, such as a cylinder or a cone. The method involves slicing the object into a series of discs, where each disc has an infinitesimal thickness. The discs’ volume is then accumulated through integration to find the object’s overall volume.

Volume of Revolution: Shell Method - Simon Fraser University

WebApr 11, 2024 · The washer method, also known as the shell method, is a formula used to find the volume of a solid that is generated by rotating the area between two curves around the x-axis. The washer method is a variation of this method that is used when the region of interest is between two curves, rather than between a single curve and the x-axis.
