Circumference of a circle is denoted as C in geometry. The formula to calculate circumference is:
C=2πr
where:
π = 22/7
r = radius
Note, radius is half of diameter (the line that touches two sides within circle and passes through the center of the circle)

The formula to calculate circle is C=2xπ x r
π, also known as pie = 22/7 = 3.143
I hope, it helps.
A circle with a radius of 5 units has a circumference of 31.42 units.
The formula for the circumference of a circle is the same, whatever its diameter. Circumference = pi*diameter.
Formula of Circumference of a circle: 3.14*Diameter of the circle. You could also do: 3.14*3.14*radius.
The formula; 2 * Pi * Radius = circumference Will calculate the circumference of a circle.
The circumference of a circle with a diameter of 7.2 is 22.62. (rounded)
