Hello all,

New here but needing some help on a few questions in involving areas no in the first quadrant.

Question 1: Find the volume of the solid generated by revolving the region bounded by y= -x^2-1 and y=x^2-2x-5 about the line y=11.

Question 2: is using the same regions about x=4. The bounded region is in quadrants 3&4 and this seems to be throwing me off.

Thanks in advance for your help.
