Volumes of Solids of Revolution / Method of Rings

In this section we will begin looking at the volume of solid of revolution. We have to first describe just what a solid of revolution is. To get a solid of revolution we begin with a function, y = f (x ) , on an interval [a,b]. Then we rotate this curve around a given axis to get the surface of the solid of revolution.  For discussion let's rotate the curve around the x-axis, although it could be any vertical or horizontal axis.  Carrying out this for the curve above gives the given three dimensional region. #### In the terms of x, The length of Kara's rectangular patio can be expressed ...
