The circumference of a circle is the distance round the outside. It can be found by multiplying 'pi' which equals 3.14 by the diameter of the circle. For example, if a circle has a diameter of 4, its circumference is 3.14 x 4 = 12.56. If you know the radius, the diameter is twice as large
The formula; 2 * Pi * Radius = circumference Will calculate the circumference of a circle.
Pi X D = Circumference. To find Diamater if you know Circumference, divide Circumference by Pi (3.14).
Diameter = Circumference/pi
You divide the circumference by pi.
Circumference = π * Diameter
diameter = circumference/pi
If you know the circumference of a circle, you can find the radius by dividing the circumference by the value of Pi (3.14159...)
You cannot find the diameter of something from its circumference unless it is a circle and, in that case, diameter = circumference/pi
Divide the circumference by Pi to find the diameter.
Divide the circumference by PI (3,14159...)
The circumference is: 32.1
Circumference = Pi * diameter
