    If you know the radius of the circle, double it to get the diameter. The radius is the distance from the center of the circle to its edge.[1] X Research source Example If the radius of the circle is 4 cm, then the diameter of the circle is 4 cm x 2, or 8 cm.
    If you know the circumference of the circle, divide it by π to get the diameter. π is equal to approximately 3.14 but you should use your calculator to get the most accurate results.[2] X Research source Example If the circumference of the circle is 10 cm, then the diameter is 10 cm/π, or 3.18 cm.
    If you know the area of the circle, divide the result by π and find its square root to get the radius; then multiply by 2 to get the diameter. This goes back to manipulating the formula for finding the area of a circle, A = πr2, to get the diameter. You can transform this into r = √(A/π) cm.[3] X Research source Example If the area of the circle is 25 cm2, divide that by π and find the ...
    Familiarize yourself with the use of a compass (the drawing tool, not the direction-finder). This is a very useful instrument in many applications, including drawing a circle's diameter, as outlined above. A divider (an instrument similar to a compass) can sometimes be used in such cases.[6] X Research source Thanks Helpful 3 Not Helpful 1
    Using geometrical formulas and equations gets easier with practice. Ask for help from someone who has worked with circles or any other geometrical figures. You're likely to find that questions of geometry will seem less challenging with a little experience. Thanks Helpful 25 Not Helpful 23

  6. How to Find the Circumference Using the Diameter. You can find the circumference of a circle given the diameter using a similar formula: C = πd. The circumference C is equal to pi times the diameter d. You can also use our circumference calculator to find this answer.

  7. To calculate the circumference of a circular shape when the diameter is given we need to use the formula, C = πd. There are two simple steps required here, Step 1: The diameter of the shape is mentioned. If not, we need to calculate it with the help of the radius and use any of the above formulas.
