C = d x pi 37.68 / 3.14 = d your diameter is 12cm
The circumference of a 13.5 diameter circle is: 42.41(diameter x pi = circumference).
If the diameter of a circle is 12 inches the circumference is: 37.7 inches (diameter x pi = circumference).
The circumference of any circle is (pi) x (the circle's diameter).
The circumference of a circle, if the diameter is 9.5 inches, is: 29.85 inches (diameter x Pi = circumference)
The circumference of a circle if the diameter is 12cm is 37.7cm
12pi 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
