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. Webabout. We’re revolving around the x-axis, so washers will be vertical and cylindrical shells will have horizontal sides. We would need to split the computation up into two integrals if we wanted to use the shell method, so we’ll use the washer method. The area of a cross section will be A(x) = ˇ(2 x)2 ˇ p x 2 = ˇ 4 4x+ x2 ˇx= ˇ 4 5x+ x2: 1

WebWe have seen two different techniques that can be used to find the volume of a solid of revolution. We summarize the washer and shell method side by side. We find the geometric quantities by noting the following. The outer … Webmore. You can always use either, the difference is that the washer method takes the cross-section of your final shape, then rotates it, while the disk method subtracts the entire volume of the shape enclosed by g (x) from the shape enclosed by f (x). If you think about it, both are the same thing, except in a slightly different order (using f ...

WebSep 21, 2024 · Method 1: Disk (washer) Method. Remember, the disk and washer method are the same thing. In the disk method, we visualize stacked circles (or pancakes, as I like to say). The washer method is the same stacked pancakes with holes (like washers or donuts). I like to complete every problem with the same thought process.
