WebDec 14, 2024 · In many cases, you could either use the shell or the washer/disk method to integrate volumes and you would get the same result. For your specific case, you could integrate elther way. 1) Washer/disk method: V = ∫ 0 2 π ( 4 2 − x 2) d y = π ∫ 0 2 ( 16 − y 4) d y = 128 5 π. 2) Shell method, V = ∫ 0 4 2 π x y d x = 2 π ∫ 0 4 x x d ... WebAnd if I did that, I'd get a shape that looks something like that. And I want to figure out the volume of that shape. And what we're going to do is a new method called the shell …

The shell method goes as follows: Consider a volume in three dimensions obtained by rotating a cross-section in the xy-plane around the y-axis. Suppose the cross-section is defined by the graph of the positive function f(x) on the interval [a, b]. Then the formula for the volume will be: If the function is of the y coordinate and the axis of rotation is the x-axis then the formula becomes: 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 … cyberchase 507

WebJul 14, 2024 · 1. I have been reading up on disk/washer, shell methods to find volume of solids of revolution, but I am having trouble with the following question: We are being asked to find the volume of the following solid of revolution: R bounded by the graph of y = x / 2, y = 3 x, y = 4, revolved about the y -axis. My thoughts so far: Use shell: V = 2 π ... WebIn the last video we were able to set up this definite integral using the shell or the hollow cylinder method in order to figure out the volume of this solid of revolution. And so now … WebDec 20, 2024 · By breaking the solid into n cylindrical shells, we can approximate the volume of the solid as. V = n ∑ i = 12πrihi dxi, where ri, hi and dxi are the radius, height and thickness of the ith shell, respectively. This is a Riemann Sum. Taking a limit as the thickness of the … In this section, we examine the method of cylindrical shells, the final method for … Shell Method - 6.3: Volumes of Revolution: The Shell Method Volume by Shells - 6.3: Volumes of Revolution: The Shell Method Gregory Hartman (Apex) - 6.3: Volumes of Revolution: The Shell Method LibreTexts is a 501(c)(3) non-profit organization committed to freeing the … cyberchase 509
