The circumference of a circle is the perimeter of the circle. It is the total length of the boundary of the circle. A person walking across a circular park, or a circular table to be bordered requires this metric of the circumference of a circle. The circumference is a linear value and its units are the same as the units of length. A circle is a round closed figure where all its boundary points are equidistant from a fixed point called the center. The two important metrics of a circle are the area of a circle and the circumference of a circle.

Prior to discussing how to calculate circumference from diameter, let us define what it is. Circumference of a circle or perimeter of a circle is the length of the complete arc of a circle. That is, the circumference would be the length of the circle if it were opened up and straightened out to a line segment. In addition, circumference is represented by the uppercase letter C and it is measured in terms of units of length like centimeters, meters, or kilometers. Diameter is a chord or a straight line segment that runs through the center point of any circle and touches two points on the circumference of a circle. It is the longest possible chord of any circle. Finding the circumference of a circle is quick and easy. If you know the length of the diameter of any given circle, then you can calculate its circumference. Save my name, email, and website in this browser for the next time I comment.
