The equation for a circle is a function in that it can be graphed and charted. One common equation is x^2 + y^2 = r^2.
Equation of the circle: (x-3)^2 +( y+13)^2 = 169
The equation of a circle centered at the origin is x2 + y2 = r2; in this case, x2 + y2 = 64.The equation of a circle centered at the origin is x2 + y2 = r2; in this case, x2 + y2 = 64.The equation of a circle centered at the origin is x2 + y2 = r2; in this case, x2 + y2 = 64.The equation of a circle centered at the origin is x2 + y2 = r2; in this case, x2 + y2 = 64.
