.

Let r be the radius of the circle.


The area of the circle is  pi%2Ar%5E2.


The regular hexagon consists of 6 equilateral triangles with the side length of r.

The area of each such a triangle is  r%5E2%2A%28sqrt%283%29%2F4%29;

hence, the area of the regular hexagon is  6r%5E2%2A%28sqrt%283%29%2F4%29 = 3r%5E2%2A%28sqrt%283%29%2F2%29.


Thus the ratio of the area of the hexagon to that of the circle is

    %283%2Asqrt%283%29%29%2F%282%2Api%29 = 0.827 (rounded).    ANSWER

Solved.
