The radius of a circle is the distance from the center to any point on the circle.
Use the distance formula:
^2\ +\ (y_1\ -\ y_2)^2})
where )
and )
are the coordinates of the center and any one of the other three points.
Be very careful about your signs when plugging in the coordinates and doing the arithmetic.
