The point (-5, 6) lies on a circle. What is the length of the radius of this circle if the center is located at (-6, 5)?

I believe you can just use the distance formula for this...since it is the center of the circle to a point on the circle \[D = \sqrt{(x2 - x1)^2 + (y2 - y1)^2}\] you have your 2 points (-6 , 5) (-5 , 6) (x1 , y1)(x2 , y2) can anyone else confirm or deny this method?

I get √2 as the radius √(-5 + 6)² + (6 - 5)² √ (-1)² + (-1)² √(1 + 1) √2
