Solution:-

The area of the shaded region will be 4.56 cm²

Step-by-step explanation:

Given the side of the square = a = 2√2 = √8 cm

=> Area of the square = side² = a² = 8 cm²

We know that the length of the diagonal of a square is given by,

d = a√2

=> d = √8 x √2 = √16 = 4 cm

Since the square is inscribed in a circle, hence the diagonal of the square will be the diameter of the circle,

=> radius = d/2 = 4/2 = 2 cm

Area of the circle = πr²

= 3.14 x 2²

= 12.56 cm²

Hence the area of the shaded region will be

Area of circle - Area of the square

= 12.56 - 8

= 4.56 cm²

Shaded area = 4.56 cm²

Step-by-step explanation:

Given ABCD is a square.

Side of square = 2\sqrt2 cm

Area of square = side × side

                         =2\sqrt2\times 2\sqrt2

Area of square = 8 cm²

Diagonal = \sqrt{ (2\sqrt{2} )^2+(2\sqrt{2} )^2}

               = \sqrt{8 + 8}

               =\sqrt{16}

Diagonal = 4 cm

Diameter of circle = Diagonal of square

Diameter of circle = 4 cm

∴ Radius of circle = 2 cm

Area of circle = πr²

                      = 3.14 × 2²

Area of circle = 12.56 cm²

Shaded area = Area of circle - Area of square

                      = 12.56 cm² - 8 cm²

Shaded area = 4.56 cm²
