WebThe equation of a circle can be found using the centre and radius. The discriminant can determine the nature of intersections between two circles or a circle and a line to prove for tangency. WebEquation of a circle. The general equation of a circle normally appears in the form \({x^2} + {y^2} + 2gx + 2fy + c = 0\). where \(( - g, - f)\) is the centre of the circle . and \(\sqrt {{g^2} + {f^2} - c}\) is the radius.. Notice that for the circle to exist, \({g^2} + {f^2} - c\textgreater0\). Look at the following worked examples. can my german shepherd eat eggs
