Answer:
Rounding to the nearest hundredth, the area of the shaded region is approximately 167.91 square yards.
Explanation:
To find the area of the shaded region between two circles with the same center, we need to subtract the area of the smaller circle from the area of the larger circle.
The area of the larger circle is:
A_outer = πr_outer^2
= π(11.9 yd)^2
≈ 445.03 yd^2
The area of the smaller circle is:
A_inner = πr_inner^2
= π(9.4 yd)^2
≈ 277.12 yd^2
Therefore, the area of the shaded region is:
A_shaded = A_outer - A_inner
≈ 445.03 yd^2 - 277.12 yd^2
≈ 167.91 yd^2
