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!!!
The radius of a circle is half of its diameter.
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
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.
The radius of a circle is half of its diameter.
radius is half diameter...so divide diameter by 2!!!
