The circumference of a circle (or its perimeter) is calculated by the formula:
L = 2пR, where
n is a mathematical constant equal to n = 3.14;
R is the radius of the circle.
Let’s calculate the circumference, the radius of which is R = 5 cm:
L = 2 * 3.14 * 5 = 31.4 cm.
Answer: The circumference is 31.4 cm.
