WebThe circumference is the diameter times pi (𝝅). Example: If the diameter is 12 then the circumference is 12𝝅 𝝅 is generally difficult to calculate, since it goes on forever you can write it in terms of 𝝅 (12𝝅). You could also times the diameter by 3.14 to estimate it. Example: If the diameter is 12 then the circumference is 37.68.
