I need to see how to solve this problem to see if I got it right, but can’t get someone to do the whole problem. HELP !

Answer:
I think it’s 226.08.
Step-by-step explanation:
Area of a circle= pi times radius squared
The radius of the whole circle is 9 ft and pi= 3.14
9 squared is 81; 81 times 3.14 is 254.34. The radius of the area that is not shaded is 3 ft. 3 squared is 9 and 9 times 3.14 is 28.26.
254.34- 28.26 = 226.08
