Circumference = Pi * 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).

the Circumference is pi times 2 times radius If you know circumference then you can find the radius. once you know the radius just multiply by 2 to find the diameter.

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
