WebApr 11, 2024 · V = pi * ∫[a, b] f(x)^2 dx . Washer Method. The washer method, also known as the shell method, is a formula used to find the volume of a solid that is generated by rotating the area between two curves around the x-axis. The washer method is a variation of this method that is used when the region of interest is between two curves, rather than ... WebYou work the method in two stages: Calculate the volume of the solid, ignoring the hole, Find the volume of the hole and then subtract it. This can be accomplished with the following integral: Example question: Find the volume of the solid of revolution bounded by y = x 2 and y = x and rotated around the x-axis. Step 1: Create a graph to help you visualize the problem. people who research aliens
