When we use the slicing method with solids of revolution, it is often called the disk method because, for solids of revolution, the slices used to over approximate the volume of the solid …

Jan 18, 2025 · We can use this fact as the building block in finding volumes of a variety of shapes. Given an arbitrary solid, we can approximate its volume by cutting it into n thin slices. When …

Take the very simple function y=x between 0 and b. Rotate it around the x-axis ... and we have a cone! The radius of any disk is the function f (x), which in our case is simply x. What is its …

The table on the next page provides a summary of the equations for the disk/washer method with respect to the axis of revolution and shows what the function variable (x or y) needs to be in …

This interactive Geogebra illustration demonstrates the idea of approximating the volume of a solid of revolution by the sum of volumes of thin disks (washers).

This calculus video tutorial explains how to use the disk method and the washer method to calculate the volume of a solid when the region enclosed by the cur...

If we think about the volume of the outer shape, once again, we can use the disk method. So at any given point in time our radius for one of our disks is going to be equal to the function.

Jun 6, 2025 · Compare the disc method vs washer method with easy tips, key formulas, and practice examples for the AP® Calculus exam.

Apr 17, 2025 · Use the disk method when there’s no hole and the shape touches the axis of rotation. Use the washer method when there’s a hole or gap between the shape and the axis.

Dec 28, 2017 · The disk and washer methods are useful for finding volumes of solids of revolution. In this article, we’ll review the methods and work out a number of example problems.
