The circumference of a circle with a diameter of 13 mm is: 40.84 mm
The circumference of a circle with a diameter of 110 mm is 345.58 mm
The diameter of a circle that has a circumference of 113 mm is about 35.97 mm
The circumference of a circle with a diameter of 55 mm is: 172.8 mm
The circumference of a circle that is 16 mm in diameter is 50.27 mm
Diameter of any circle = circumference/pi
The circumference of the circle with a diameter of 64 mm is 64*pi = about 201 mm
Circumference of a circle = π × diameter = π × 80 mm = 80π mm ≈ 251 mm
If the diameter of a circle is 3mm the circumference is: 9.424 mm
circumference = diameter X pi diameter = circumference/pi diameter = 55 mm/3.1416 diameter = 17.5 mm
If the diameter is 25 mm then the circumference is 78.54 mm.
The diameter of a circle with a 19 mm circumference is about 6.048 mm (d = c divided by Pi).
