Use the shell method to find the volume of the solid formed when a hole of radius 2 is drilled symmetrically along the axis of a right circular cone of radius 4 and height 6. Model the situation on a set of axes by placing the center of the base of the cone at the origin and the cone's axis along the positive y-axis. Set up the integral that gives the volume of the solid using the shell method. Use nonnegative and increasing limits of integration.
