WebThe Disk/Washer Method: The Disk/Washer Method uses representative rectangles that are perpendicular to the axis of revolution. Therefore, we have the following: Or in three-dimensions: Our formula states: V ()[]f ()y []g()y dy d =∫ c − π 2 2 where f ()y is the right curve, g()y is the left curve, and dy is the width. WebDisc method: revolving around x- or y-axis. Let R R be the region in the first quadrant enclosed by the x x -axis, the y y -axis, the line y=2 y = 2, and the curve y=\sqrt {9-x^2} y = 9− x2. A solid is generated by rotating R R about the y y …
