The radius is one half of the diameter. If the diameter is 20, the diameter is 10.
you have multiplythe radius by 2 to get the diameter
Width, or diameter as it is more commonly known = 2*radius.
Radius of a circle = diameter/2
diameter = 2*radius
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.
the radius is half the diameter
The radius is half the diameter.
divide diameter by 2 = radius
The diameter of the semicircle will be twice the radius.
The radius is one half of the diameter. If the diameter is 20, the diameter is 10.
you have multiplythe radius by 2 to get the diameter
Double the radius
Divide the diameter by 2.
To find diameter, multiply raduis by two.
You times the radius by 2.
Divide the diameter by 2.
