The region bounded by and the coordinate axes is rotated about the -axis. Calculate the volume of the resulting solid.

Sketch the region so you can visualize the flag.

The axis of rotation (the pole) is the -axis.

The resulting solid will be a cone.

Which axis contains the radius () and which contains the height ()?
