3 meters, 1/2 of the diameter
Diameter of a circle is defined as twice the radius. So if diameter is 12, the radius is 6.
the diameter of a circle is double the radius so if the radius is 12 cm then the diameter is 24 cm
the radius is one half the diameter,or 6
Radius of a circle is half of its diameter and so 12/2 = 6 cm
