Want this question answered?
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?
This is very, very basic math. The radius is half of the diameter. My 9 year old daughter knows this.
It is: 2 to 1
Length of diameter:length of radius = 2:1
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 .....)
pi
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.
