A right cylinder has height h and radius r. It is sliced by a plane that is tangent to one circular base at A and intersects the other at diameter BC. What is the volume of slice ABCD?
Note that BO=CO=DO=r, AD=h, BC is perpendicular to DO, and AD is perpendicular to DO.

It isn't a cone, it is the sliced edge of a cylinder, like the lower section in the image (link above). Except, sliced edge touches the base of the cylinder.
