Hint:

Why don't you translate the whole configuration down 2 units?

Then you would "find the volume of the solid formed by revolving the regions bounded by the graphs of y = 1 - x^2 and the y=2 (the x-axis) about the x-axis"

Hint #2

By the "Just-look-at-it Theorem" the x-intercepts are ±1 and there is symmetry, so you could just take it from 0 to 1 and double that.
