Answer 1

• The area of the shaded region is 7.722 cm²

Explanation:

We know that:

• Diameter of circle = 6 cm
• Radius of circle = 3 cm
• Side of square = 6 cm
• π = 3.142

Using the above information, let's find the area of the square, then the area of a circle.

• Area of square = Side²
• => Area of square = 6²
• => Area of square = 36 cm
• => Area of circle = πr²
• => Area of circle = 3.142 x r x r
• => Area of circle = 3.142 x 3 x 3
• => Area of circle = 28.278

Now, let's subtract the area of the circle from the area of a square. (I.e., Area of square - Area of circle)

• => 36 - 28.278
• => 7.722

Hence, the area of the shaded region is 7.722 cm².

Answer 2

shaded area = 7.72 cm²

Explanation:

square area is length * length = 6 * 6 = 36 cm²

circle area = πr² = 3.142 * 3 * 3 =28.278 cm²

so shaded area = 36 cm² - 28.278 cm² = 7.72 cm²
