The first step to solve this problem is to solve for the
area of the square. The formula for the area of the square is:
A = a^2
Where a = measurement of the side of the square
A = 7^2
A = 49 cm^2
The second step is to solve for the area of the circle. The diameter
of the circle can be drawn out of the side of the square which is 7 cm.
Therefore, the radius of the circle is 3.5 cm. The formula in solving the area
of the circle is:
A = pi (r)^2
A = 3.14 (3.5)^2
A = 3.14 (12.25)
A = 38.465 cm^2
To solve for the area of the shaded region, you have to
deduct the area of the circle to the area of the square.
Asquare – Acircle = Area of the shaded region
49 cm^2 – 38.465 cm^2 = 10.54 cm^2 is the area of the shaded
region
