How to work out circumference of a circle using diameter

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. Here we shall aim at understanding the formula and calculation of the circumference of a circle. The circumference of a circle is its boundary or the length of the complete arc of a circle. Let us understand this concept using an example. Consider a circular park shown below. If a boy starts running from point 'A' and reaches the same point after taking one complete round of the park, a distance is covered by him. This distance or boundary is called the circumference of the park which is in the shape of a circle.

How to work out circumference of a circle using diameter

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.
