Circumference of circle
180⁰
The circumference of a circle is the length of the outer boundary of the circle. It is the distance traveled around the periphery of the circle.
The formula to calculate the circumference of a circle is given by:
C = 2πr
where
C = circumference of the circle
π (pi) = a mathematical constant, approximately equal to 3.14
r = radius of the circle
To find the circumference, you simply need to know the value of the radius of the circle. If the radius is not given, you can calculate it by dividing the diameter by 2.
For example, if the radius of the circle is 5 cm, then the circumference of the circle would be:
C = 2πr
C = 2π x 5
C = 10π
C ≈ 31.4 cm
Therefore, the circumference of the circle with a radius of 5 cm is approximately 31.4 cm.
