Shell method examples and answers

Web1 Answer. Sorted by: 2. You're right; your shell radius is incorrect. For instance, when x = 5, the radius of your shell should be r = 0. When x = 2, the radius of your shell should be r = 3. In general, the radius is r = 5 − x. So we find that the volume is: 2 π ∫ − 3 5 ( 5 − x) ( 2 x + 15 − x 2) d x = 2048 π 3. WebDec 21, 2024 · When the axis of rotation is the y -axis (i.e., x = 0) then r ( x) = x. Let's practice using the Shell Method. Example 7.3. 1: Finding volume using the Shell Method.
