I THINK!! (keyword) that you just take the right x vale and the left x value (in that order) At least that's what I got from my notes because I don't have it written down anywhere Wait, I just found YET ANOTHER example problem that messes up my train of thought and makes me think I did the entire homework for nothing (don't you love those?) Whenever they give you 0 < X < pi Your bounds are 0 and pi
I'm confused too...sorry I think I made it worse for you =/
You set your two equations equal if the bounds aren't given to you. If you are revolving about x, you use the x values. If you are revolving about y to have to take the answers you get when setting them equal and plug them into the original equation. 1-6 you could just look at the picture. The others you had to set = to find the bounds.
