The circumference of circle with radius 12cm is 75.4cm
If the diameter of a circle is 69mm then the circumference is: 216.8mm (diameter x pi = circumference).
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
12pi cm
circumference = π x diameter ⇒ diameter = circumference ÷ π = 12 cm ÷ π ~= 3.8 cm
Circumference = pi x diameter. So the circumference of a circle with diameter 12 cm = pi x 12 = 37.7 cm (1 decimal place.)
The circumference of circle with radius 12cm is 75.4cm
Circumference: 12*pi = 37.699 cm rounded to three decimal places
perimeter of a circle = circumference = pi x diameter perimeter = 3.1416 x 12 = 37.7 cm
using the formula circumference=diameter X pi: circumference=diameter X pi circumference/pi=diamter X pi/pi circumference/pi=diameter therefore, diameter=circumference/pi diameter=12mm/3.14 diameter=3.821mm
C = d x pi 37.68 / 3.14 = d your diameter is 12cm
C=3.14D C=12x3.14 C=37.7+12=49.7
If the diameter of a circle is 69mm then the circumference is: 216.8mm (diameter x pi = circumference).
Well, the diameter would be 24, so the circumference would be π (pi, 3.14) times the diameter.24 x 3.14 = 75.36Apply this to all your math when using circumference. BTW if it is telling you the DIAMETER, just multiply by pi to get your answer.
Diameter of a circle = circumference/pi
