That's not to say it's an impossible question, it's just ambiguous. For example, if you had a circular region, say $x^2+y^2=1$, and you wanted to revolve it around its vertical axis of symmetry (the line $x=0$), you can still do so, but the usual approach with disk or shell integration would give you twice the desired spherical volume. It gets more ambiguous when you don't have a symmetric region, like a general polygon.
