Diameter facts for kids
In geometry, the diameter of a circle is a line from one side directly to the opposite side through the centre. It can also be defined as the longest chord of a circle. These can both describe the diameter in a sphere too.
The letter d or the symbol ⌀ are often used as a symbol for the diameter. The diameter's length is often called the diameter itself.
