The diameter is twice the radius - so, using your example, the diameter would be 6.
the radius is half the diameter
The radius is half the diameter.
Radius = Diameter/2.
I guess you mean:"How do you find the radius if you are given the diameter?"You take the diameter and divide it by 2.
Radius of a circle = diameter/2
divide diameter by 2 = radius
The radius is one half of the diameter. If the diameter is 20, the diameter is 10.
radius is half diameter...so divide diameter by 2!!!
The diameter by definition because a diameter of a given object is twice its radius.
The diameter of the semicircle will be twice the radius.
you have multiplythe radius by 2 to get the diameter
Diameter =2R(whare R-Radius of the circle)
