Answer:

D. 4.5

The Area is 63.585

Explanation:

So the diameter is twice the size of the "r" or radius so divide 9 by 2

which is 4.5

The formula for a circle is πr^2

4.5 times itself is 20.25

times pi or 3.14 is 63.585

Hope this helps!

Because the radius is 4.5 inches we use the area formula for a circle ( pi * radius squared) to find the answer so

4.5 * 4.5 * 3.14 which will equal 63.585 inches squared

Hope this helps
