WebFeb 8, 2015 · For the disk/washer method, the slice is perpendicular to the axis of revolution, whereas, for the shell method, the slice is parallel to the axis of revolution. Example. Okay, … 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 …
WebThe Shell Method is a technique for finding the volume of a solid of revolution. Just as in the Disk/Washer Method (see AP Calculus Review: Disk and Washer Methods ), the exact answer results from a certain integral. In this article, we’ll review the shell method and show how it solves volume problems on the AP Calculus AB/BC exams.
