Question

what is the general equation of circle

Answer 1

The center-radius form of the circle equation is in the format (x – h)2 + (y – k)2 = r2, with the center being at the point (h, k) and the radius being "r". This form of the equation is helpful, since you can easily find the center and the radius

Answer 2

Gneral equation of circle is x^2 + y^2 = r^2 (or) (x-h)^2 + (y-k)^2 = r^2.
