    \( \color{Black}{\Rightarrow (x - h)^2 + (y - k)^2 = r^2 }\) \(r\) is the radius. \((h,k)\) is the center. Lol I'm sorry(and late) in telling this but this is an equation of a circle :P

    general equation of a circle with radius \((h,k)\) radius \(r\) is ... what parth said

    Compare the equation you are given with the equation of a circle I gave.

    Radius is r.... I think you meant center \((h,k)\).

    in your case \(r^2=36\) and so \(r=6\) should be able to find the center

    Lol it's funny to think how both r and (h,k) are radii :P
