Q: A ball of radius 17 has a round hole of radius 8 drilled through its center. Find the volume of the resulting solid.
A: 4500pi
I am mostly confused about the question...If we have a bead-like object, then how are we suppose to rotate it to make a solid? I guess I am just having a hard time visualizing this? In regards to the math part, I suppose I just need to find the volume of revolution for the cylinder and the ball separately then subtract them? Any help would be appreciated, thanks!
