The length of a radius is not the length of a diameter. The diameter is two times the length of the 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.
Radius = 1/2 of diameter
The diameter is double the radius.
The radius is 1/2 of the diameter, so if the radius is 20 units then the diameter is 40 units. You multiply the radius by 2 to get the diameter.
Diameter
Diameter = exactly double the radius, so the diameter is always longer.
The diameter is twice as large as the radius.
Diametre is, since diametre = 2*radius
It's longer than both. The circumference - is the distance around the circle... The diameter - is the distance across the circle, passing through the centre... The radius - is the distance from the centre of the circle to the edge.
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
