Circumference is equal to 2 times pi (3.1416) times one half of the diameter (the radius).
So, if the diameter is 2 cm, then the circumference would be the product of (2) times (3.1416) times (1), or 6.2832 cm.
Circumference is equal to diameter times Pi.c = Pi * d
diameter times pi

How can i find circumference if you know diameter?
Circumference = Pi * diameter
How do you find circumference if you know diameter?
If you know the diameter and need the circumference you times the diameter of the circle by 3.14 also known as pie. That is how you get the circumference by only knowing the diameter. :)
How do you calculate the diameter and the circumference of a circle?
Doubling the radius will give the diameter and times this by pi will give the circumference of the circle.
How do you calculate the radius from the circumference?
Of a circle: divide the length of the circumference by the value of Pi (about 3.14159). The answer is the diameter. Half of the diameter is the radius
How do know how to make out circumference and diameter if you only know the radius?
If you know the radius, then Diameter = 2 x (radius) Circumference = (pi) x (diameter) or Circumference = 2 x (pi) x (radius)
