Okay so I'm having trouble formulating this integral. The region is bounded by: and rotated about: I tried using shells.. It didn't really work for me Thanks, CC

Okay so you did R meaning the radius of the big circle and r for the little. How did you find the bounds?

Okay, so why did you do R^2 - r^2?

The little circle minus the big circle. Okay I guess I just don't get how you got root 7 to 4

Okay I guess I just don't get how you got root 7 to 4 is the vertex of the hyperbola at the left end of the defined region to be rotated. is the right boundary of the region to be rotated. I recommend you meet with your instructor ... this is all very basic material which should have been covered in class.
...plug in zero for y in other words. Thank you for your concern.
