Formula of confidence interval of one sample proportion:
Confidence interval 
A circle equation is (x – h)^2<span> + (y – k)^</span>2<span> = r^</span><span>2 where (h,k) is the center and r is the radius. Now all we have to do is plug in the variables.
Since (h,k)=(5,4) and r= 6
The answer would be C.
