WebThe Method of Cylindrical Shells. Let f (x) f ( x) be continuous and nonnegative. Define R R as the region bounded above by the graph of f (x), f ( x), below by the x-axis, x -axis, on the left by the line x =a, x = a, and on the right by the line x= b. x = b. Then the volume of the solid of revolution formed by revolving R R around the y y ... WebIf it’s parallel to your slices, each slice will trace out a cylindrical shell as it revolves about the axis. If, on the other hand, it’s perpendicular to your slices, each slice will trace out a washer or disk as it revolves about the axis. In either case the proper method of integration has automatically been determined for you.

WebThe shell method asks for height of "cylinders" parallel to your axis of revolution: you're usually given the function in terms of y, so if you're revolving around y, that's easy. Similarly, the disk method asks for the radius of a disc that is perpendicular to your axis of revolution; well, if you're revolving about the x-axis, that radius is ...
