1028: Makeup Exam: Problem 2

A regular convex polygon is a equilateral and equilangular polygon. Compute C1, the perimeter of a regular convex polygon with all corners lying on a single circle of unit radius (radius is 1.0). Compute C2, the perimeter of a regular convex polygon with all edges tangent a single circle of unit radius. In the program one takes the number of edges N from keyboard and show the C1 and C2 separated by a comma. The format for C1 and C2 should have three digits in fractional part.
For example: N=3
