The circumference of a circle with a diameter of 8 centimeters is = 8*pi cm
The circumference is equal to the diameter times pi (π).So for a circle with a circumference of (8π) centimeters, the diameter is 8 centimeters.
A simple formula to calculate the circumference of a circle: so in this case:
If the radius of a circle is 8 cm, the circumference will be: 50.3 cm (C = r x 2 x Pi).
Area = 50.265 cm2Circumference = 25.132 cm
