This is going to be 3 pi over 6. This is 3 pi over 6 minus 2 pi over 6. Pi over 3 is 2 pi over 6, pi over 2 is 3 pi over 6. And we end up with 3 of something minus 2 of something, you end up with 1 of something. We end up with 1 pi over 6. And we are done. We were able to find the volume of that wacky, kind of gutted out truffle.
