Answer:
The answer is 28.26
Explanation:
Why? Ok so here it is:
The formula is (pi)(r)squared
In this case, you will replace pi with 3.14 and replace r with 3 because that's the radius.
So it would be (3.14)(3)
You would get 9.42
Now you just need to square it
When squared, you'll get 28.26 inches squared
