The circumference of a circle if its radius is 13cm is: 81.68 cm
Circumference of the circle: 13*pi = 40.841 cm rounded up to 3 decimal places
Diameter of a circle = circumference/pi
The circumference of a circle with diameter of 4.4 is about 13.82
The circumference of a circle if the diameter is 25.8 is: 81.1
The circumference of a circle if its radius is 13cm is: 81.68 cm
Circumference of the circle: 13*pi = 40.841 cm rounded up to 3 decimal places

The formula for the circumference (C) of a circle is C = 2πr where r is the radius. But, the diameter (D) of a circle is twice the radius so this formula can be written C = πD. C = π x 13 = 40.841 cm (3dp)
If the diameter of a circle is 69mm then the circumference is: 216.8mm (diameter x pi = circumference).
Radius = about 13cm Diameter = about 26cm
Diameter of a circle = circumference/pi
Diameter of a circle = circumference/pi
The circumference of a 13.5 diameter circle is: 42.41(diameter x pi = circumference).
If a circle has a circumference of 8 the diameter is: about 2.546 (circumference divided by pi = diameter).
The circumference of a circle if the diameter is 12cm is 37.7cm
The circumference of a circle with a diameter of 6cm is about 18.85cm
