Lateral Area of a Frustum Problem: Figure 8-6n shows that a frustum of a cone is a difference Figure 8-6n between two similar cones, one of radius andslant height R and L, the other of r and l. Bythe properties of similar triangles,Use this fact and clever algebra to transformthe area of the frustum so that it is in terms ofthe average radius and the frustum slantheight,
