What is the approximate area of the shaded region if the area of the square is 144 square meters and the area of the circle is 50.24 square meters?

• 94.76 square meters

• 93.76 square meters

• 92.76 square meters

• 91.76 square meters

Why is the area of the circle considered an approximation?

• Because the circle is not perfectly round

• Because the square's side length is not exact

• Because pi is approximated as 3.14

• Because the radius is not exact
