Radius of a circle = diameter/2
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.
The radius is half of the diameter. If the diameter is 48, you can calculate the radius by dividing the diameter by 2. Therefore, the radius is 48 ÷ 2 = 24.
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!!!
