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. :)

Divide the known circumference by pi to find the diameter of the circle.

Pi X D = Circumference. To find Diamater if you know Circumference, divide Circumference by Pi (3.14).

To Find Diameter:Multiply circumference by 0.3183, ordivide circumference by 3.1416Other things to do with circles:To find Circumference:Multiply diameter by 3.1416, ordivide diameter by 0.3183To Find Radius:Divide diameter by 2, ormultiply circumference by 0.15915, ordivide circumference by 6.28318

If you know the radius, then Diameter = 2 x (radius) Circumference = (pi) x (diameter) or Circumference = 2 x (pi) x (radius)

Divide the known circumference by pi to find the diameter of the circle.

To find the diameter of a circle, you will either need to know the area or its circumference. If you know the area: diameter = 2 x squareroot(area / Pi) If you know the circumference diameter = circumference / Pi

Diameter = circumference/pi

Multiply the diameter by pi (~3.14) to get the circumference.

If you know the circumference of a circle, you can find the radius by dividing the circumference by the value of Pi (3.14159...)
