Acircle is drawn within a square as shown. what is the best approximation for the area of the shaded region? use 3.14 to approximate pi.

The answer is around 168.56

work :

the side of the square is 28 in

so the diameter of the circle is 28 in, too(look at the picture)

then the radius is 14 (28/2)

the area of the circle is


the area of the square is


so the area of the shaded region will be around:


good luck
