Answer
15.7 meters squared.
Step-by-step explanation:
First you have to find the area of the small circle, using the formule A = 3.14(radius squared). So, 3.14(4) =12.56. Then you have to find the area of the bigger circle. A = 3.14(3 squared). A = 3.14(9) = 28.26. Finally, you subtract the area of the smaller circle from the bigger circle. 28.6 meters - 12.56 meters = 15.7 meters squared.
