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!!!
you have multiplythe radius by 2 to get the diameter
The formula to calculate radius is Pi x Diameter. So, if the radius is 7, the diameter is 14. Then, do 14 x pi (3.14) and your circumference will be 43.96
Width, or diameter as it is more commonly known = 2*radius.
Circumference = diameter*pi
well if the radius is given then the diameter is : d=2r. as for in a circle the diameter is : d=2(pi)r pi=3.14
Double the Radius to Calculate the Diameter.
diameter = 2 * radius
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.
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.
