Find volume by integration
WebSep 7, 2024 · Example \(\PageIndex{5B}\): Finding a Volume Using a Double Integral. Use polar coordinates to find the volume inside the cone \(z = 2 - \sqrt{x^2 + y^2}\) and above the \(xy\)-plane. Solution. The region \(D\) for the integration is the base of the cone, which appears to be a circle on the \(xy\)-plane (Figure \(\PageIndex{10}\)). WebUse a three-dimensional integral anytime you get that sensation of wanting to chop up a three-dimensional region into infinitely many pieces, associate each piece with a value, then add them all up. One place where this is surprisingly useful is just finding the volume of three-dimensional regions by adding up all the tiny volumes d V dV d V d, V.
