Answer:
   216.66 yd²
Step-by-step explanation:
One way to find the area of a ring like this is to multiply its centerline length by the width of the ring.
Here, the diameter of the circle that is the centerline of the ring is 23 yd. The circumference of that circle is ...
   C = πd = 3.14(23 yd) = 72.22 yd
Then the ring area is ...
   (72.22 yd)(3 yd) = 216.66 yd² . . . area of shaded region
