Answer:
C
Step-by-step explanation:
Answer: 819.73 yd²
<u>Step-by-step explanation:</u>
= 
= 
= 29 * 30
= 870
= π(4)²
= 16π
≈ 50.27
Area of the park = 
= 870 - 50.27
= 819.73
So if the formula is A=(pi)r^2, find the area of the entire circle:
A=(pi)(13^2)=530.66cm
then find the area of the little circle:
A=(pi)(3^2)= 28.26cm
then subtract the little circle from the big circle:
530.66cm-28.26cm= 502.4cm
and there you go. Hope this helps!
