WebOct 22, 2024 · The Disk Method Example 6.2.3: Using the Disk Method to Find the Volume of a Solid of Revolution 1 Exercise 6.2.3 Rule: The Disk Method for Solids of Revolution around the y -axis Example 6.2.4: Using the Disk Method to Find the Volume of a Solid of Revolution 2 Exercise 6.2.4 The Washer Method Rule: The Washer Method WebInclude the vertical line, x = − 2, as a reference. We’ve included the cylindrical shell as a guide too. Find the volume of the solid using the formula, V = 2 π ∫ a b ( x – h) [ f ( x) – g ( x)] x d x. That’s because we’re rotating the region about the vertical line, x = − 2. Hence, we have the following:

WebDisk/Washer and Shell Methods A solid of revolution is a solid swept out by rotating a plane area around some straight line (the axis of revolution). Two common methods for nding the volume of a solid of revolution are the (cross sectional) disk method and the (layers) of shell method of integration. To apply these methods, it is easiest to: 1. WebIt is a modification of the Disk Method for solids with a hole in the middle. It is called the "washer method" because the cross-sections look like washers. The formula for the washer method is. V = ∫ a b ( R 2 − r 2) d x. where R is the outer radius of the solid and r is the inner radius of the solid.
