Volume of Revolution: Shell Method - Simon Fraser University

WebThe shell method is a method of finding volumes by decomposing a solid of revolution into cylindrical shells. Consider a region in the plane that is divided into thin vertical strips. If each vertical strip is revolved about the \(x\)-axis, then the vertical strip generates a disk, as we showed in the disk method.However, if this thin vertical strip is revolved about the … WebShell integration (the shell method in integral calculus) is a method for calculating the volume of a solid of revolution, when integrating along an axis perpendicular to the axis of revolution.
