Hello, viet!

Iassumethis is a Calculus problem . . .

A ball of radius 15 has a round hole of radius 8 drilled through its center.

Find the volume of the resulting solid.Code:|15 * * * *:::::|:::::* *:::::::|:::::::* *- - - -8+ - - - -*P | * | * - - * - - - - + - - - - * - - * | *15 | * | * * | * * | * * * * |

The circle has equation: .

The region between the circle and is revolved about the x-axis.

The coordinates of point are: .
