| If the perimeter of a square is 24 cm, then its side is 24/4 = 6 cm.
The diameter of a circle circumscribed about a square is equal to the diagonal of this square. By the Pythagorean theorem, the square of the diagonal is equal to the sum of the squares of the two sides:
D ^ 2 = a ^ 2 + a ^ 2 = 6 ^ 2 + 6 ^ 2 = 2 * 36;
D = 6√2 cm.
The radius is equal to half the diameter, which means that the radius of the circumscribed circle around this square is 3√2 cm.
It is known that the side of a regular hexagon is equal to the radius of the circumscribed circle. This means that the required side of a regular hexagon is 3√2 cm.
