The diameter of a circle is a straight line segment that passes through the center of the circle and has both of its endpoints on the circle's boundary. It is the longest distance that can be measured within a circle. In other words, the diameter is twice the length of the radius, which is the distance from the center of the circle to any point on its boundary.

## Formula

To calculate the diameter of circle, you can use the following formula.

Diameter of Circle = \(2 r \)
