### What is Meant by the Diameter?

In Mathematics, the diameter is the term which is most frequently used in Geometry. The diameter is closely related to the two-dimensional shape circle. We know that the circle is a closed 2D figure where all the points on the surface of the circle are equidistant from the centre point. The distance between the surface and the centre of the circle is the radius “R”. The diameter of the circle “D” is double the radius. The diameter is defined as the straight line where it passes from one side of the circle to the other side through the centre point. The formula to calculate the diameter when the radius is given is D = 2R
