K kensington Jul 2010 86 0 Jul 28, 2010 #1 Im having a bit of problem with the following question: Find the volume of the solid obtained by rotating the region bounded by the curves y=0, y= sinx, 0<=x<=pi; about the line y=-2 Im not exactly sure how to solve it with it being bounded by 3 curves help please?
