If the diameter of a circle is 69mm then the circumference is: 216.8mm (diameter x pi = circumference).
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
The circumference of a circle 14' in diameter is about 43.98'
The circumference of a circle with a diameter of 51m is: 160m
The circumference of a circle, if the diameter is 15cm, is about 47.12cm
The circumference of a circle with diameter of 15cm is about 47.12cm
C = ~47.12 cm
If 15cm is the diameter then the radius is 7.5cm If the circumference is 15cm then the radius is 7.5/pi cm
The formula for the circumference of a circle is C = 2πr where r is the radius. This formula can also be expressed as C = πd where d is the diameter as the diameter is twice the radius. C = 15π = 47.12cm (2dp)
double the radius to get the diameter = 30 multiply by pi (3.1415...) = 92.245 cm
The perimeter of a full circle (circumference) is "pi" times the diameter. So the perimeter of a semi-circle will be half that; Perimeter = (pi/2) x (diameter).
circumference = 15*pi cm
If the diameter of a circle is 69mm then the circumference is: 216.8mm (diameter x pi = circumference).
The cylinder's circumference is approximately 50.27cm
Diameter of a circle = circumference/pi
Diameter of a circle = circumference/pi
