egoroff_w [7]

Answer:

$36\pi in^2$

Step-by-step explanation:

1. The formula for the area of a circle is $A=\pi r^2$

2. You are already given the radius. (r)

3. Plug the radius into the equation. You should get $A=\pi (6)^2$

4. Leave in terms of pi, so (6)^2 is 36. (6x6)

5. This leaves you with $36\pi in^2$

** units are important. Don't forget them (inches)
