I guess it is simplifying the expression:

Hello!
Your answer should be 26.85.
We can use the formula of pi d or 2 pi r for the circumference.
You would get 5 pi.
But since its not a full circle you would divide it in half and get 2.5 pi.
2.5 pi is equal to 7.85.
Now we can use the equation 7.85 + 7 + 7 + 5
That would equal our answer... 26.85!
Hope this helps!
We know, the measure of whole circle = 360
So, ACB = 360 - AOB
ACB = 360 - 30
ACB = 330
In short, Your Final Answer would be Option A
Hope this helps!
