The area of the shaded area = the area of the square - the area of the circle = 30.9 cm².
<h3>How to Find the Area of the Shaded Area?</h3>
The area of the shaded area = the area of the square - the area of the circle.
Find the area of the side length of the square:
Area of a circle = s², where s is the side length of the circle.
Therefore, we have:
144 = s²
Take the square root of both sides
√144 = √s²
12 = s
s = 12
The side of the square = 12 cm.
The diameter of the circle = side length of the square = 12 cm
Radius of the circle (r) = 12/2 = 6 cm.
Area of the circle = πr² = π(6²) ≈ 113.1
The area of the shaded area = 144 - 113.1
The area of the shaded area = 30.9 cm².
