Circle Graph Formula

The radius form of the circle equation will be in the default format of (x - h)2 + (y - k)2 = r2, with the (h, k) be the center. This equation is helpful, since you can easily calculate the center and the radius. The below given is the Circle graph formula for calculation of coordinates points and radius for the circle to be drawn. Just substitute the radius (r) value in the Circle graph equation formula to get the radius value along with the coordinates (0,0).


x2 + y2 = r2


x = Coordinate One
y = Coordinate Two
r = Radius
