The circumference of a circle if the diameter is 12cm is 37.7cm
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
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
To find the diameter of a circle when given the circumference, you can use the formula: circumference = π x diameter. In this case, the circumference is 37.68cm. So, 37.68 = π x diameter. To solve for the diameter, you would divide 37.68 by π, which is approximately 3.14. Therefore, the diameter of the circle would be approximately 12 cm.
C=3.14D C=12x3.14 C=37.7+12=49.7
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.
If the diameter of a circle is 69mm then the circumference is: 216.8mm (diameter x pi = circumference).
Diameter of a circle = circumference/pi
