The center of the circle is the point which all other points on the circle are equidistant from.
MN is a radius; this means it is the distance from the center of the circle to the outside edge. N is on the outside edge of the circle, so M is the center.
So the decrees would be 0.11 because if you add 9.55 with 0.11 you would get 9.66 then to make sure it’s right you subtract 9.66 by 0.11 and you would get 9.55. So the answer is 0.11
