When a regular hexagon is inscribed in a circle, the side length of the hexagon is equal to the radius of the circle.

Viewing the regular hexagon as six equilateral triangles, the apothem of the hexagon is the altitude of an equilateral triangle with side length 12; the length of the apothem is (sqrt(3)/2) times the length of the side.

A: the length of the apothem is which is (to 2 decimal places) 10.39.

The area of the hexagon is the area of the 6 equilateral triangles. The area of an equilateral triangle wiht side length s is .
B: The area of the hexagon is which is (to the nearest whole number) 374.
