Triangle ABC is rotated completely around side BC, sweeping out a solid in space. Find the volume of the solid. AB = 8, AC = 12, CB = 8
The resuting solid will equal the difference in volumes of the cones formed by the rotation of ADC - the rotation of ADB =
pi/3 * AD^2 *( DC - DB) =
pi/3 * 7.94^2 * ( 9 - 1) ≈ 528.15
