After thinking about it I realized where I was going wrong. I was thinking that I could bisect the torus at y5 and solve for half the volume and then double it. I finally realized that the volume of the inner part would actually be less then that of the outer part as it travels less distance to complete the full rotation.

Example 1.7. 1. A very long insulating cylinder is hollow with an inner radius of a and an outer radius of b. Within the insulating material the volume charge density is given by (R) R, where is a positive constant and R is the distance from the axis of the cylinder.
