| The area of the square is equal to the square of the side, we find the side of the square:
Skv = a ^ 2;
a = √Sq = √8 = 2√2 cm2 – side of the square.
The radius of a circle circumscribed about a square:
R = a / √2 = 2√2 / √2 = 2 cm.
The side of a regular hexagon inscribed in a circle is equal to its radius:
b = R = 2 cm.
The area of a regular hexagon is determined by the formula:
Sш = 3√3 * b ^ 2/2;
Ssh = 3√3 * 2 ^ 2/2 = 3√3 * 4/2 = 6√3 ≈ 10.39 cm2.
