Diameter = Circumfrence/pi = 13/pi = 4.14 cm (approx)
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 diameter of a circle with the circumference of 3.25 is: 1.034
If the circumference of a circle is 17.27, the diameter is: 5.5
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)
Radius = about 13cm Diameter = about 26cm
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 diameter of 19, the circumference is: 59.7 (diameter x Pi = circumference)
The circumference of any circle is (pi) x (its diameter). If diameter = 1 then Circumference = pi .
A circle with a circumference of 11.25 has a diameter of: 3.581
The circumference of a circle with a diameter of 25 is: 78.54
If the diameter of a circle is 9 the circumference is: 28.3
