This is from my calculus class.

Thanks for taking your time.

Use the shell method to nd the volume of the solid formed 1when a hole of radius 3 is drilled symmetrically along the axis of a right circular cone of radius 8 and height 12. 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. Select the correct choice below and ll in the answer boxes to complete your choice. {Type exact answers.) on. I ( )dx 03. I [ ldy The volume is . {Type an exact answer.}
