Answer:

28.27square miles

Explanation:

The area of a circle is πr² (pi times the radius squared)

The radius is 3

Square the radius, it becomes 9

9 times 3.14 is 28.27

add square units (in this case, miles) to the end of your answer

A = pi x r x r

= pi x 3 x 3

= 9 pi

Or

28. 27433388

However, 9 x 3.14 =28.26

So, answer is 28.26 Square miles

Hope this helps!
