diameter to radius ratio (for same circle) is 2:1
The ratio of radius to diameter for any circle is 1/2
They are not the same. Diameter is twice the size as radius.
No. Radius is half the diameter.
It is: 2 to 1
It depends on the ratio of what of the circle? Its circumference, diameter, area?
This is very, very basic math. The radius is half of the diameter. My 9 year old daughter knows this.
Length of diameter:length of radius = 2:1
diameter ------------- Diameter. The R (radius) of a circle multiplied by two equals the diameter.
The length of a radius of a circle is half of the diameter of the same circle. So, diameter is always twice the radius.
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 .....)
