No, 2 radii makes a diameter, because the diameter is the line which goes across the circle and exactly in the middle, and radius is the line from the circumference to the center.
So r/2 = d
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.
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 diameter is double (two times) the radius, no matter what the radius is.
The diameter of a circle is twice its radius
A circle's diameter is twice its radius.
To find the diameter, you just multiply the radius by two.
the radius is a line from the middle of a circle to a point of the circle. the diameter is two times the radius.
Multiply by two. The diameter is twice the radius.
The diameter is equal to half of the radius. So take the value of the diameter and divide it by two and that is your radius.
radius = diameter divided by two
The radius of a circle is half of the diameter! So, if the diameter was four inches, the radius would be two inches!
