Which method would you use to revolve the region bounded between y = x 2 - 4x + 5 and y = x - 1 from x = 2 to x= 3 about the y-axis? A. You can use either the Washer method or Shell method but the Washer method is easier to set up in this case. B.
WebDec 28, 2024 · A washer is like a disk but with a center hole cut out. The formula for the volume of a washer requires both an inner radius r1 and outer radius r2. We’ll need to know the volume formula for a single washer. V = π ( r22 – r12) h = π ( f ( x) 2 – g ( x) 2) dx. WebThe DISK method is pretty straight forward and its used when the axis of rotation is perpendicular to the d(x or y). It is pretty much the same as the washer method, but washer has a whole.
