Answer:
8 ft^2
Explanation:
Since the area of the circle is pi*radius^2, we can plug the values in and get that the area of the circle is 3.14 (approx.) * (6/3)^2, which equals to 3.14*9 ft^2, which equates to 28.26 ft^2.
Hence, the exact area left is 36 - 28.26 ft^2 = 7.74 ft^2, which is closest to 8 ft^2.
Hope this helped!
