MATLAB: How to plot a circle

circle plot

Hi Everybody,
I am trying to plot a circle with radius= 190 km, and the centre of circle is (2.55, 101.46)both are in degree. If I have to change in km also are become like this (283.87, 11295.0345)km. The question is how can I determine the centre of circle by symbol? and the sketch has been attached here would be useful because I do not know how to plot like this? Could you please help me?

radius = 190;
centerX = 2.55;
centerY = 101.46;
rectangle('Position',[centerX, centerY, radius, radius],...
    'Curvature',[1,1],...
    'FaceColor','w');
axis square;

I don't know what "determine the centre of circle by symbol" means, but I can tell you from the code that the center of the circle is at (x, y)=(2.55, 101.46) but I don't know what you mean when you say "both are by degree". What does a pair of degrees mean? Aren't x and y in km? How are they in degrees? What does that mean?
