The circumference of a circle = 2*pi*radius or diameter*pi
Circumference of a circle is 2πr (two x Pi x the radius of the circle)Pi is usually taken as 3.14 for simple calculations - see here http://en.wikipedia.org/wiki/Pi for a longer determination of Pi.The radius is half the diameter.Thus, a circle with a diameter of 6cm has a circumference of 18.84cm
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 14' in diameter is about 43.98'

It is: 2 to 3 respectively
If the diameter of a circle is 69mm then the circumference is: 216.8mm (diameter x pi = circumference).
Diameter of a circle = circumference/pi
Diameter of a circle = circumference/pi
A ≈ 28.27cm2
The circumference of a 13.5 diameter circle is: 42.41(diameter x pi = circumference).
If a circle has a circumference of 8 the diameter is: about 2.546 (circumference divided by pi = diameter).
The formula for the circumference of a circle is C = 2πr, where C is circumference, π is pi (approx. 3.142), and r is the radius. So, for a circle with a radius of 6cm, C = 2(3.142)(6cm) = 18.852cm Rounding to the proper number of significant figures, this answer would be 20cm.
The circumference of a circle if the diameter is 12cm is 37.7cm
The circumference of a circle 14' in diameter is about 43.98'
