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

WebThere is another method, which instead of creating disk-slices will create cylindrical shell-slices. These cylindrical shell-slices are created by cutting through the solid with cylinders that wrap symmetrically around the axis of rotation as shown in Figure 3.15. Webnope the idea of shells is that you integrate circumferences*heights which covers both sides (since you get a full circle) from integrating just 1 side (you can see it from the picture that as you integrate outwards you integrate the top and bottom areas at the same time) ( 6 votes) Show more...
