What is the Equation of a Circle?

In geometry, a circle is a two-dimensional round shaped figure where all the points on the surface of the circle are equidistant from the centre point (c). The distance from the centre of the circle to the surface is called the radius (R). The equation of a circle can be calculated if the centre and the radius are known. Thus the equation of a circle is given by
(x-h)2 +(y-k)2 = r2
Where
(h, k) – centre coordinates
r – radius
