The circumference of a circle can be calculated using the formula C = πd, where C is the circumference, π is a constant approximately equal to 3.14159, and d is the diameter of the circle. In this case, the diameter is 5 cm, so the circumference would be C = π * 5 cm = 15.70796 cm.

Pi times the diameter of a circle gives its circumference. Since the radius is 5 cm, the diameter is 10 cm, and pi x 10 cm is the answer, or 31.4159 cm.
If a circle has a diameter of 5 the circumference is: 31.4
The diameter of a circle who's circumference is five is: 1.592
The circumference of a circle if the diameter is 5 inches is 15.7 inches.
The circumference of a circle if the radius is 5 cm is: 31.42 cm (radius x 2 x Pi = circumference).
