Diameter - Wikipedia
Diameter - Wikipedia

In geometry, a ,diameter, of a circle is any straight line segment that passes through the centre of the circle and whose endpoints lie on the circle. It can also be defined as the longest chord of the circle. Both definitions are also valid for the ,diameter, of a sphere.. In more modern usage, the length of a ,diameter, is also called the ,diameter,.
