WebMar 26, 2016 · The disk/washer method cuts up a given shape into thin, flat disks or washers; this makes it useful for shapes with circular cross-sections, like, well, cones. The following practice question asks you to apply the disk method for just this purpose. Practice question. Use the disk method to derive the formula for the volume of a cone. WebNov 16, 2024 · Back to Problem List 2. Use the method of disks/rings to determine the volume of the solid obtained by rotating the region bounded by y = 7 −x2 y = 7 − x 2, x = −2 x = − 2, x = 2 x = 2 and the x x -axis about the x x -axis.

Web2.2.1 Determine the volume of a solid by integrating a cross-section (the slicing method). 2.2.2 Find the volume of a solid of revolution using the disk method. 2.2.3 Find the volume of a solid of revolution with a cavity using the washer method. In the preceding section, we used definite integrals to find the area between two curves. 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. part man part machine all cop
