Yeah you are right, it is only external. I figured it out by cutting it into smaller parts like you said and then using disks and washers. Thank you for your help.
I have not been instructed to use any particular method, I just need to find a solution to the problem. For these types of problems I generally use disks or washers to find the volume, but I guess the "tricky" part of this problem is that the bound area crosses the the axis on which it's...
I have to find the volume of the solid whose area is bound by the equations y=-x+3 \ and \ y=x^2-3x as it revolves around the x and y axis. I approached it by finding the center of mass and then using Pappus's theorem:
M_{x}=\int^{3}_{-1} \frac{1}{2}((-x+3)^2-(x^2-3x)^2)\,dx = \frac{64}{15}...
