WebDec 29, 2024 · We know that the equation of the circle is: (x-h)^2+ (y-k)^2= R^2 (x − h)2 + (y − k)2 = R2 Where (h, k) is the coordinate of the center of the circle and R is the radius of the circle. A circle is divided into lower and upper semicircles. Let the coordinate of a center be (0, 0) and the radius of a circle is R. So, h = 0, and K = 0; WebThe General Form of the equation of a circle is x 2 + y 2 + 2gx +2fy + c = 0. The centre of the circle is (-g, -f) and the radius is √(g 2 + f 2 - c). Completing the square.
