Diameter

The diameter of a circle is a line segment that passes through the center and has its endpoints on the circle. It is the longest distance that can be measured across a circle. The diameter is always twice the length of the radius of the circle.

The formula to calculate the diameter of a circle is:

Diameter = 2 * Radius

Where,

Diameter = Length of the diameter

Radius = Length of the radius

The diameter is an important measurement in understanding the size and proportions of a circle. It is used in various mathematical and scientific calculations involving circles, such as finding the circumference, area, or volume of circular objects.
