WebDec 20, 2024 · By breaking the solid into n cylindrical shells, we can approximate the volume of the solid as. V = n ∑ i = 12πrihi dxi, where ri, hi and dxi are the radius, height and thickness of the ith shell, respectively. This is a Riemann Sum. Taking a limit as the thickness of the shells approaches 0 leads to a definite integral.

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. WebAgain, we are working with a solid of revolution. As before, we define a region R, R, bounded above by the graph of a function y = f (x), y = f (x), below by the x-axis, x-axis, and on the left and right by the lines x = a x = a and x = b, x = b, respectively, as shown in Figure 2.25(a).
