The relationship between the radius and the diameter of a circle is that: radius = diameter /2
The radius is half the diameter of a circle.
The diameter of any circle is twice its radius
The diameter of a circle if twice the length of the radius.
The radius is half the diameter.
The radius X 2 = diameter.
Diameter is twice the radius, D=2R
The relationship is that the radius is half of circle's diameter.
In a circle its radius is half the size of its diameter.
The diameter of a circle is twice its radius
The radius of a circle is half the diameter so if the radius of a circle is r, then the diameter is 2r.
The diameter of a circle is twice its radius
