1. The problem statement, all variables and given/known data A ball of radius 12 has a round hole of radius 7 drilled through its center. Find the volume of the resulting solid. 2. Relevant equations 3. The attempt at a solution I tried to do it as though it is a ball with a radius of 12 missing a ball with a radius of 7 from its center and got an answer around 2900. But it is actually a ball with a radius of 12 with a hole of radius of center, if that makes sense. Like you could see through the ball. I have no idea how to approach this..
