<Dd> V = πr h . </Dd> <P> This formula holds whether or not the cylinder is a right cylinder . </P> <P> This formula may be established by using Cavalieri's principle . </P> <P> In more generality, by the same principle, the volume of any cylinder is the product of the area of a base and the height . For example, an elliptic cylinder with a base having semi-major axis a, semi-minor axis b and height h has a volume V = Ah, where A is the area of the base ellipse (= πab). This result for right elliptic cylinders can also be obtained by integration, where the axis of the cylinder is taken as the positive x-axis and A (x) = A the area of each elliptic cross-section, thus: </P>
