Websolid of revolution are the (cross sectional) disk method and the (layers) of shell method of integration. To apply these methods, it is easiest to: 1. Draw the plane region in question; 2. Identify the area that is to be revolved about the axis of revolution; 3. Determine the volume of either a disk-shaped slice or a cylindrical shell of the ... As we know the washer method and shell method both apply in the calculations. But the uses of both methods are vital and beneficial method of integration. Sometimes, it is best to use the washer method in case of finding volume of solid revolutions and sometimes the shell method works more … See more Suppose that we have a region R, bounded between the curves y=f(x) and y=g(x) from x = a to x = b as shown in a figure. If we take this region and revolve it around the y axis, we obtain the following solid of revolution … See more For understanding the washer method, we will recall the washer method about the y-axis. Suppose that we have a region bounded between … See more Let R be the region bounded in the first quadrant by the curve y = 1-√x, on the x-axis and the y-axis. We want to determine the volume of the solid generated when r is revolved about the … See more

WebLesson 10: Washer method Solid of revolution between two functions (leading up to the washer method) Generalizing the washer method Washer method rotating around horizontal line (not x-axis), part 1 Washer method rotating around horizontal line (not x-axis), part 2 Washer method rotating around vertical line (not y-axis), part 1 Web(If you think about it, the washer method is just the disk method twice, but you subtract one disk from the other!) Anyhow, your intuition is more or less correct. The 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. how many people does a 14 inch cake feed
