The radius is half the diameter of a circle.
The diameter of any circle is twice its radius
The radius is half the diameter.
The relationship is that the radius is half of circle's diameter.
When d=diameter and r=radius d=2r or r=1/2d
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 is half the length of the diameter of a circle.
it doesn't-__-
The radius X 2 = diameter.
Diameter is twice the radius, D=2R
The relationship is that the radius is half of circle's diameter.
The circumference is ALL the way around the circle, while the radius is only HALF way into the middle of the circle. I'm guessing you meant "What is the relationship between the radius of a circle and its circumference?" Radius is half of the diameter of a circle, circumference is PI times diameter; therefore, the circumference is PI times two times radius.
