We revolve around the x-axis a thin vertical strip of height y = f(x) and thickness dx. This generates a disk of radius y and thickness dx whose volume is dV. Volume of the ellipsoid. We get the volume of the ellipsoid by filling it with a very large number of very thin disks, that is by integrating dV from x = -2 to x = 2. hager fox electric

"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 shells approaches 0 leads to a definite integral. " - Disk method formula around x axis
