In the figure below there is a circle inscribed inside a square. The length of one side of the square is 7 inches; determine the approximate area of the shaded region inside the square, (figure not drawn to scale)
Explanation: Area of square \(= 7^2 = 49\). Radius of circle \(= \frac{7}{2} = 3.5\). Area of circle \(= \pi r^2 = \frac{22}{7} \times 3.5 \times 3.5 = 38.5\). Shaded-এর area \(= 49 - 38.5 = 10.5\) sq inches.
