the circumference of a circle is equal to 2*pi*R, so just divide by pi(3.141)
The circumference of a circle is the length of the circle's perimeter.
The radius of a circle is the distance from its centre to its circumference. If a circle has a radius of r units then the length of its circumference is 2*pi*r units.
Since pi is the ratio of a circle's circumference to its diameter, multiply the diameter by pi (about 3.14159) to get the circumference.
It depends on what information you do have.

the fraction of the circle covered by the arc
The circumference of a circle is the length or distance around the outside of the circle.
circumrenceThe length around a circle is called the circumference
The total circumference is (arc length) times (360) divided by (the angle degrees)
The length around a circle is the circumference The length across a circle is the diameter
Times length times width
It is called the circumference.
It is called its circumference!
