The length of one side of the square in the picture below is 8. All the four circles are inscribed within the square and of equal radius. What is the area of the shaded region? (figure not drawn to scale)
Explanation: square- এর প্রত্যেক বাহু = 8. circle - এর radius \(= \frac{8}{4} = 2\). Area of square \(= 8^2 = 64\). Area of 4 circles \(= \pi (2)^2 \times 4 = 16\pi\). Shaded region এর area \(= \frac{64-16\pi}{4} = 16-4\pi\).
