The area of the shaded region is 81.14 cm^2.
Since AB is a diameter of the circle, the length of AB is equal to twice the radius of the circle, which is 2 * 6.2 cm = 12.4 cm.
Since ABCD is a square, the side length of the square is equal to half the length of AB, which is 12.4 cm / 2 = 6.2 cm.
The area of the square is equal to the side length squared, which is 6.2 cm * 6.2 cm = 38.44 cm^2.
The area of the circle is equal to pi * radius squared, which is 3.14 * 6.2 cm * 6.2 cm = 119.58 cm^2.
The area of the shaded region is equal to the area of the circle minus the area of the square, which is 119.58 cm^2 - 38.44 cm^2 = 81.14 cm^2.
Working:
Area of circle = pi * radius^2
= 3.14 * 6.2^2
= 119.58 cm^2
Area of square = side length^2
= 6.2^2
= 38.44 cm^2
Area of shaded region = area of circle - area of square
= 119.58 cm^2 - 38.44 cm^2
= 81.14 cm^2
Therefore, the area of the shaded region is 81.14 cm^2.
