Twelve synchronized swimmers are forming a circle. the location of those swimmers are (13,-2) (-1,-2) and (6,-9). a 4th swimmer will appear in the center of the circle. where would the center swimmers need to be located?

The swimmer will need to be at the point (6, -2).

The point (6, -2) is equidistant from and in the middle of all three of the points. Therefore, it would be the center of the circle. You can graph them and plot a circle through the points to be sure. 

I’m confused as to what you are asking 66 2/3 percentage wise
