A regular hexagon with sides of 3" is inscribed in a circle. Find the area of a segment formed by a side of the hexagon and the circle.
---------------------
radius of the circle = 3"
Area of circle = 9*pi
Area of hexagon = ns^2*cot(180/n)/4, n = 6, s = 3
Area of hexagon = 54*cot(30)/4 = 54sqrt(3)/4 = 13.5sqrt(3)
Difference = 9*pi - 13.5sqrt(3) for the whole circle and hexagon
Divide by 6
= 1.5*pi - 2.25sqrt(3) sq inches
