The Cartesian coordinate system is the structure we use to graph points in two dimensions. Something that has two dimensions is a surface. The Cartesian coordinate system (also called the Cartesian plane, or just “the plane”) is a flat surface (like the cover of a book) that extends forever in all directions.

The formulas we use to find surface area of revolution are different depending on the form of the original function and the axis of rotation.
