Both the radius and the diameter are measurements which define a circle. The diameter is the distance straight across a circle from one edge to the other, passing through the midpoint of the circle. The radius is half of the diameter. Therefore, it is incorrect to say that either comes before the other.
Radius = Diameter/2 Diameter = 2* Radius
to get the diameter from the radius you simply multiply the radius by 2 since the radius is half the diameter. d=2r where d = diameter and r = radius
A radius is one half of a diameter so divide by two to get from a diameter to a radius. Or you can multiply the radius by 2 to get to the diameter.
The length of a radius is not the length of a diameter. The diameter is two times the length of the radius.
radius = diameter/2
The radius is half the diameter. So, if the diameter is 8, then the radius is 4.
A radius is half of a diameter. Example Diameter:4 Radius:2
The diameter of a circle is twice its radius.
the radius is one-half the diameter radius = diameter/2 diameter = 2 x 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.
The relationship between the radius and the diameter of a circle is that: radius = diameter /2
diameter is longer. radius is half of diameter
