Answer 2

The diagonal of square=8 cmWe have to find the area of region lying outside the circle and inside the square.We know that diagonal of square =side*√2Thus side*√2=8 cmTherefore side = 8/ root 2 = 5.65 cm.The radius of circle = 5.65/2 = 2.825 cm.Thus required area = side²-  radius²= 31.9225-25.0718=6.85 cm
