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
