The radius is half the diameter.
Multiply the radius by 2.
Divide the diameter by 2.
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
Assuming that daimeter = diameter andraduis = radius, you simply divide diameter by 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 diameter of a circle is the length of a straight line that goes through the exact center of a circle. The radius of a circle is the length of a straight line that starts at the exact center and reaches the circle. The radius is half the length of the diameter.
