How to work out circumference of a circle using diameter

Understanding what a circumference of a circle is and how to calculate it is crucial as you move to higher level math. In this article you will learn the answers to the following questions. The circumference of a circle is the distance around the outside of the circle. It is like the perimeter of other shapes like squares. You can think of it as the line that defines the shape. For shapes made of straight edges this line is called the perimeter but for circles this defining line is called the circumference. There are two other important distances on a circle, the radius r and the diameter d. The radius, the diameter, and the circumference are the three defining aspects of every circle. Given the radius or diameter and pi you can calculate the circumference. The diameter is the distance from one side of the circle to the other at its widest points. The diameter will always pass through the center of the circle. The radius is half of this distance.

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.
