What is the ratio of the radius of a circle to the side of a pentagon that can be made inside the circle?
Q. In other words, what do I multiply the radius by to find a segment that is one fifth of the circle?

A. Assuming the pentagon is a regular pentagon, the two shapes share the same center. If we call the distance from the pentagon's center to one of its corners R, then using some trigonometry, we can find the length of the side in terms of R. Here's a picture of an inscribed pentagon to help you: If we draw R, the line from the center to the vertex, and the apothem, which is the perpendicular bisector of the polygon's side ( we get a right triangle whose sides are R, the radius, A, the apothem, and 1/2 S, half of the side. We know the angles of a regular pentagon measure 108 degrees. Since we have only half of the angle, that angle measures 54 degrees (this is the angle between R and 1/2 S). Using some trig: cos 54 = (1/2 S)/R 1/2 S… [cont.]
