There are 2 formulas for finding the circumference of the circle.If the radius diameter is given,we use the formula �d.When the radius is given,we use the formula 2�R.
* * * * *
But there are also other formulae for when the area is given, or the length of an arc and the angle subtended at the centre or on the circumference are known. Plus many more. Basically, the question is too poorly specified to find a single answer.
Also, the above formulae assume that the shape is a circle. But it could be an ellipse, for example.
