To find the circumference of a circle when the radius is given, you can use the formula: Circumference = 2 * π * radius.
Given that the radius of the circle is 2 units and using the value of π as 3.14, we can substitute these values into the formula to find the circumference:
Circumference = 2 * 3.14 * 2
Circumference = 12.56 units
Therefore, the circumference of a circle with a radius of 2 units is 12.56 units.
