Question

1. explain the relationship between the radius and the diameter.

Explanation:

The diameter of a circle is twice the length of its radius. Mathematically, if \(r\) is the radius of a circle, then the diameter \(d = 2r\). This relationship is fundamental in circle - related geometry. For example, if a circle has a radius of \(3\) units, its diameter is \(2\times3=6\) units.

Answer:

The diameter of a circle is twice the radius. So, \(d = 2r\) where \(d\) is the diameter and \(r\) is the radius.
