The radius of the circle is the length of a straight line stretching from the center of the circle to the line of circumference. Now that you know the formulas and what they are used for lets work through some example problems. Circle Formula Circle is a particular shape and defined as the set of points in a plane placed at equal distance from a single point called the center of the circle. So here is the formula.
