The circumference of a circle if the radius is 5 cm is: 31.42 cm (radius x 2 x Pi = circumference).
The circumference of a circle 5cm in radius is about 31.42cm
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.
Circumference of circle: 2*pi*5 = 31.416 cm rounded to 3 decimal places
If a circle has a diameter of 5 the circumference is: 31.4
