Diameter refers to the distance across the circle from a point to other while passing through the center. Twice the radius of the circle is the diameter. The circle has no ends and so its distance across the outer layer is called circumference. The distance around the circle, that is perimeter is called as the circumference of the circle. In the diameter of a circle from circumference formula, substitute the circumference value by dividing it by pi value (pi = 22/7 or 3.14).

Where,

D = Diameter

C = Circumference

The circumference of a circle is the measure of the distance around the outside edge of a circle. Use the above diameter of a circle from circumference formula to find the circle diameter when only the circumference value is given as input.
