WebJul 19, 2024 · The general equation for a circle is x 2 + y 2 + 2 g x + 2 f y + c = 0, where h = − g and k = − f. The radius is then r = g 2 + f 2 − c. The book says: If g 2 + f 2 − c = 0, then it's a point circle. If g 2 + f 2 − c > 0, then it's a real circle. If g 2 + f 2 − c < 0, then it's an unreal or imaginary circle. What does that mean? circles Share Cite WebMar 26, 2024 · The equation of a circle is (x-h)²+(y-k)²=r². The coordinates for the center of the circle are (h, k), so to find the center of the circle, solve for h and k.
