I'm trying to find the standard equation of a circle given the circles center and a point that it passes through. I can't find which formula is actually the "standard." Would it be the Center-Radius form (x-h)^2 + (y-k)^2 = r^2 or the General form

x^2 + y^2 + cx + dy + e = 0. I see the Center-Radius form more commonly used but the general form just yells out standard.
