Update:
Occasionally you can actually solve cross-sectional area problems without heavy integral work (as we saw on the Unit 5 test, where there was a problem that actually involved constructing half of a sphere). So, just pay attention to what shapes are being created in each problem, and before you decide to take a more complex approach, make sure there isn't a sleeker way involving a simple generic shape equation.
