# Circle Equations Based On Radius Worksheets

How Does the Radius of Circle Help Us write an Equation for it? Forming equations is an essential aspect of any mathematical procedure. Informing those equations, you find out that there are different parameters that are important in those processes. For an equation of a circle, the radius is that important parameter. Radius, by definition, is the distance between the center of the circle and the surface of the circle. Based on the different forms of equations, i.e., standard form of the equation and general form of the equation, both require radius for calculation. Even if the center of the circle lies on origin, you only need a radius to find its equation.
