Disk method to find volume
WebIf that clue isn't enough to give you a clear visualization, step away from this example for a minute and imagine a different one, where we have the line segment traced by x = 2 from y = -1 to y = 3, and we rotate it around the vertical line at x = -2. This would simply be a cylinder centered at x = -2. Now imagine that we change the vertical ...
Disk method to find volume
Did you know?
WebIn this section, we examine the method of cylindrical shells, the final method for finding the volume of a solid of revolution. We can use this method on the same kinds of solids as the disk method or the washer method; however, with the disk and washer methods, we integrate along the coordinate axis parallel to the axis of revolution. WebVolume of a representative disk = DVi = p[f(xi)]2Dx. To determine the volume of entire solid of revolution, we take each approximat-ing rectangle, form the corresponding disks (see the middle panel of Figure 6.12) and sum the resulting volumes, it generates a representative disk whose volume is DV = pR2Dx = p[R(xi)]2Dx.

WebIf the axis of revolution is the boundary of the plane region and the cross sections are taken perpendicular to the axis of revolution, then you use the disk method to find the volume of the solid. Because the cross section of a disk is a circle with area π r 2 , the volume of each disk is its area times its thickness.
