A complete lesson that completely covers the calculation of volumes by cross sections. Most calculus textbooks ignore this topic, or jump straight to very difficult examples. This lesson begins with a review of geometry. Most calculus students have a difficult time writing an expression for the area of a cross section. This review eases them into it, from squares and rectangles up to equilateral triangles and semicircles. There is one volume problem given that is meant to be worked through as a
