In this lesson, we learn about solids of revolution and how to calculate their volumes using integrals. We see examples of how to find the volume of solids formed by revolving a planar region and discuss how to handle cross-sections that are not disks, but rather, disks with holes called washers. We are also shown how to calculate the volume of a torus using integration.
