Given a cylinder of radius R and height H, what is the formula for finding the volume of ​​the larger of the two geometric figures obtained by cutting the cylinder with a plane perpendicular to the bases, and placed at distance (minimum) D from the axis of symmetry of the cylinder, with R > 0, H > 0, 0 < D < R ?

I think that you should use term plane instead of "an axis" – pedja Nov 8 '11 at 19:20
Could you maybe show a picture of what you want to happen? – J. M. Nov 8 '11 at 23:34
Is this what you mean ? – pedja Nov 9 '11 at 7:26
Yes, that is what I mean. – Claudio Floreani Nov 9 '11 at 14:21

Area of a circular segment =area of wedge - area of triangle =$\frac{R^{2}}{2}(\theta-\sin\theta)$

angle of wedge = $\theta=2cos^{-1}{\frac{D}{R}}$

"Area of Wedge" here means Circular Sector – Claudio Floreani Nov 17 '11 at 22:28
