∙ 13y agoThe 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 = Circumfrence/pi = 13/pi = 4.14 cm (approx)
Diameter of a circle = circumference/pi
The circumference of a circle with diameter of 4.4 is about 13.82

Diameter = Circumfrence/pi = 13/pi = 4.14 cm (approx)
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).
If a circle has a diameter of 19, the circumference is: 59.7 (diameter x Pi = circumference)
