Disk washer and shell method equations

WebApr 19, 2010 · With the washer/disc method, if you're given a function f (x) and you want to rotate it, say around the x-axis - then you simply take a representative rectangle with its base on the x-axis (and its length going up to the function). Then the width/base of the representative rectangle will be dx, while the length will be f (x). WebDec 21, 2024 · Let a solid be formed by revolving the curve y = f(x) from x = a to x = b around a horizontal axis, and let R(x) be the radius of the cross-sectional disk at x.

WebWhat is the Shell Method Formula? Let R R be the region bounded by x = a x = a and x = b x = b. Suppose we form a solid by revolving it around a vertical axis. Let r(x) r ( x) represent the distance from the axis of rotation to x x and h(x) h ( x) be the height of the shell. The volume of the solid is given by WebThe shell method is a method of finding volumes by decomposing a solid of revolution into cylindrical shells. Consider a region in the plane that is divided into thin vertical strips. If each vertical strip is revolved about the \(x\)-axis, then the vertical strip generates a disk, as we showed in the disk method.However, if this thin vertical strip is revolved about the …

WebFor any given x-value, the radius of the shell will be the space between the x value and the axis of rotation, which is at x=2. If x=1, the radius is 1, if x=.1, the radius is 1.9. Therefore, the radius is always 2-x. The x^ (1/2) and x^2 only come into play when determining the height of the cylinder. Comment.
