Answer:
B. 7.73 square units
Explanation:
The area of the shaded region = area of the square - area of the inscribed circle
Radius of the circle (r) = 3 units
Side length of the square (s) = diameter of 2*radius of the inscribed circle = 6 units
Area of square = s² = 6² = 36 square units
Area of inscribed circle = πr² = π3² = 28.27 square units
Area of shaded region = 36 - 28.27 = 7.73 square units
