Question I'm really having issues grasping the Volumes of Solids of revolution. I could use some help solving this question, it isn't very hard. 1. Let R be the region bounded by y = x2 and y = x + 2. Find: a) the area of R b) the volume of the solid if R is rotated about the x-axis c) the volume of the solid if R is rotated about the the line x = 4 2. Relevant equations 3. The attempt at a solution Basically this is what I've gotten. a) Area = ∫((x+2)-(x2))dx = (x2/2 + 2x) - (x3/3), evaluated over the interval (-1,2) = 4.5 b) this is what I did but I don't know if it is right ∏∫((x+2)2 - (x2))dx = ∏∫((x2+4x+4) - x4) dx = ∏(x5/5 - x3/3 -2x2 -4x) evaluated from (-1,2) = 72∏/5 c) I'm not sure how to start this one.
