Webabout. We’re revolving around the x-axis, so washers will be vertical and cylindrical shells will have horizontal sides. We would need to split the computation up into two integrals if we wanted to use the shell method, so we’ll use the washer method. The area of a cross section will be A(x) = ˇ(2 x)2 ˇ p x 2 = ˇ 4 4x+ x2 ˇx= ˇ 4 5x+ x2: 1 WebExamples We’ll do several examples to see how the shell method works and compares with the disk method. EXAMPLE 6.13. Consider the region enclosed by the curves y = f( x)= 3 + , = 2, and the x-axis. Rotate the region about the y-axis and ﬁnd the resulting volume. SOLUTION.

Web2. 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. as desired. Share.
