One minute, I will scan my attempt

anonymous · Answer

Ok I can't really get it to scan right now, but basically, my issue is that for some reason, I am subtracting the volume of  y=x by the volume of y=x^2, and I know the radius for each will be 2 - f(x), where f(x) is either x or x^2, whichever one I am getting area for. 

But, when I solve out the integral for area, I am getting a -ve answer. Why?
