In order to calculate the circumference of a circle one must use a specific formula. The mathematical formula is C = D x 3.14. This translates to the circumference being equal to the diameter multiplied by 3.14, which is the equivalent to pi.

In order to convert the area of a circle to the circumference of the circle, divide by the radius and multiply by two. The formula for the circumference of a circle is pi times the diameter.
There is a constant relationship between the radius of a circle and its circumference. This is expressed in a formula.
the formula is: circumference= p*diameter
it is the formula of circumference of circle
To find the circumference of a circle, you can use the formula C = πd, where C is the circumference, π is a constant approximately equal to 3.14159, and d is the diameter of the circle. Given that the diameter of the circle is 69mm, you can substitute this value into the formula: C = π * 69mm ≈ 216.769mm. Therefore, the circumference of the circle is approximately 216.769mm.
