area-of-a-surface-of-revolution

In this lesson I explain the relationship between the lateral area of a right circular cone allows us to find the Area of a Surface of Revolution.

Rule for Area of a Surface of Revolution at 16:37 ,

Example with a horizontal axis of rotation at 19:11 NOTE: at 19:44 I should say "2PI times the definite integral from a to b..."

Example with a vertical axis of rotation at 28:02 ,

Example finishing with numerical integration with a calculator 33:57
