consider a circle of radius 1, and corresponding inscribed and circumscribed polygons with the number of sides n = 3, 4, 5, 6, and 8.
A: For each n = 3, 4, 5, 6 & 8, what are the areas of the inscribed and circumscribed polygons with n sides?

For an inscribed ngon, circle radius is r
A = (r^2 *n sin(2pi/n))/2
For the circumscribed ngon
A = r^2 *n tan(pi/n)
