Topic: Geometry
Subtopic: Area of Surface of Revolution

Overview

In this lesson we will use definite integrals to find the area of the surface of a solid of revolution. If the solid is a regular shape, such as a cylinder, then we have a formula to find its surface area. However, if the curve is spun to generate the solid is irregular, then calculus is needed to find its surface area. The plan will be, as usual, to find the area of a tiny piece of the surface then add the little areas up to get the surface area..
