What is the approximate area of the shaded region? 178.5 square meters
64 square meters
13.76 square meters
21.5 square meters

C) 13.76 square meters

Step-by-step explanation:

Find the area of the square and subtract it with the area of the inscribed circle. The area of the square is 8m*8m=64 m^2. The area of the circle is πr^2=π(8/2)^2=π(4^2)=16π=50.27m^2. Their difference will be the area of the shaded region. So the area of the shaded region is 64-50.27=13.73m^2, so your closest choice would be C.
