the radius is half the diameter
When you have the radius of a circle and you are trying to find the diameter, multiply the radius by two; the answer is the diameter. If you have the diameter and want to find the radius, divide the diameter by two; the answer will be the radius. The diameter is 54 centimeters.
The diameter is twice the radius. So multiply the radius by 2
Diameter = 2*Radius
If you are given the radius of the circle, you can use the formula: diameter = 2*radius If you are given the circumference of the circle, you can use the formula: diameter = circumference/pi
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.
radius is half diameter...so divide diameter by 2!!!
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.
