If a line is horizontal, it is not a curve and the radius is infinity. What are the units of your numbers?
Your question does not make sense to me.
its an arc definition curve with pts A, B, C and have to find the radius of the curve
The center of the circle containing those three points is located where the perpendicular bisectors of AB and BC intersect. Get the equations of the bisectors and solve for their intersection point.
