WebApr 10, 2024 · Using the washer method, we pick a value of y in between y = 0 and y = 1, we draw a horizontal line segment through the region R revolving this line segment around the line x = -¼ gives us this surface of a washer. So the volume by washer method is: V = ∫ 0 1 π ( ( O u t e r R a d i u s) 2 − ( I n n e r R a d i u s) 2) In this case, WebOct 22, 2024 · The formulas for the volumes of: a sphere Vsphere = 4 3πr3, a cone Vcone = 1 3πr2h and a pyramid Vpyramid = 1 3Ah have also been introduced. Although some of these formulas were derived using geometry alone, all these formulas can be obtained by using integration. We can also calculate the volume of a cylinder.
