Volume of a Wedge in a Cylinder
A right circular cylinder is cut by two planes to form a wedge. One plane is perpendicular to the axis of the cylinder (the floor), and the second plane through a diameter makes an angle with the floor. Calculate the volume of the wedge for any angle .
This is based on problem 55, Section 6.2, p. 423 of . It was also addressed by James Stewart in example 9, Section 6.2, p. 452 of  and by Edwards and Penney in example 7, Section 6.2, p. 383 of .
