Introduction to Determining Volumes by Slicing

What you’ll learn to do: Find the volume of a solid of revolution using various methods

In the preceding section, we used definite integrals to find the area between two curves. In this section, we use definite integrals to find volumes of three-dimensional solids. We consider three approaches—slicing, disks, and washers—for finding these volumes, depending on the characteristics of the solid.
