diameter ------------- Diameter. The R (radius) of a circle multiplied by two equals the diameter.
Lets see: diameter is the longest line across a circle (goes through the center) radius is one half the diameter Pi is the ratio of the circumference to the diameter. (3.14159 .....)
As pi is the ratio of the ratio of the circumference (C) of any circle to its diameter (d), the circumference of a circle in terms of pi is: C = pi x d The circumference of a circle is pi times its diameter or 2 pi times its radius (since a diameter is 2 times the 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
The radius is half the diameter. So, if the diameter is 8, then the radius is 4.
diameter to radius ratio (for same circle) is 2:1
The ratio of radius to diameter for any circle is 1/2
No because the radius of a circle is half of its diameter.
0:5
It depends on the ratio of what of the circle? Its circumference, diameter, area?
It is: 2 to 1
Length of diameter:length of radius = 2:1

The earth/moon radius ratio is about 3.67/1 and the mass ratio is about 80/1.
Radius = 1/2 of diameter.The ratio is 1/2 = 0.5.That's true for all circles, from microscopic to humongous, doesn't matter.
I think you mean "radius". It's half of the diameter.
