Volume and the Slicing … WebEthan Dlugie. 10 years ago. It really depends on the situation you have. If you have a function y=f (x) and you rotate it about the x axis, you should use disk (or ring, same thing in my mind). If you rotate y=f (x) about the y axis, you should use shell. Of course, you can always use both methods if you can find the inverse of the function.
