This is how I would set it up...
This is basically integrating the area of a cross-section, which has . Then we see that the "radii" are given by (6 - f(x)) and (6 - g(x))
Where f and g are the given functions x^2 and 1.
Find the volume of the solid obtained by rotating the region (in both the first and second quadrants) bounded by the given curves about the specified axis.
