you double the radius to find the diameter.
diameter = 2*radius
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.
circumference = pi * 2radius (diameter) so to find radius you use circumference/(2 x pi) this will find radius ----
the radius is half the diameter
The radius is half the diameter.
the radius is half the diameter
Yes, the radius is half of the diameter, therefore the diameter is twice the radius.
Divide the diameter by 2.
Radius is diameter divided by two. Diameter is radius times two or circumference divided by pi. Circumference is diameter times pi. Pi is roughly 3.14
The diameter is twice the radius. So multiply the radius by 2
The radius of a circle is half of the diameter. Radius= Diameter divided by 2
