Find the volume of the solid obtained by rotating the region A in the figure about x=−6.
Assume b=6, a=2.
Then, find the volume of the solid obtained by rotating the region 𝐵 in the figure about 𝑥=−3.
Assume b=4 and a=2.
I think I need help with the basic concept too because I'm stuck. For the first part, I tried doing the doing the disk formula for the equation, but I don't understand how to rotate around x=-6. Could someone show me the steps for the question? Thanks.
