Hello! I've seen volume calculations involving cutting a wedge from a cylinder where the wedge cuts down to the centre of the circle (i.e. the length of the straight edge will be the diameter of the cylinder). I was looking for hints on working out the area of a wedge cut from a cylinder where the wedge goes straight across from one side of the cylinder to the other; if that makes sense. If not, here's my poor attempt at a drawing to illustrate: Anyone know any websites or any hints? As I say, the only ones I found pertain to wedges where, I believe, the angle of the cut remains constant (where the cut is from the centre), I believe the angle changes in my example. Thanks in advance.
