Length of diameter:length of radius = 2:1
diameter to radius ratio (for same circle) is 2:1
No because the radius of a circle is half of its diameter.
It depends on the ratio of what of the circle? Its circumference, diameter, area?
The diameter of a circle is the length of a straight line segment going through the circle and with endpoints on the circle itself. A ratio is a comparison of two numbers using the operation of division. That means that there is no such thing as the ratio of a circle. However, there is a ratio of the circumference of the circle (the length of the path around the circle) and its diameter. That ratio has the value pi, which is about 3.141592653589793...
The radius of a circle is the distance from the center to any point on the circle. The diameter is twice as much; it is the length of a line segment from one point on a circle to another point on it that passes through the center. Pi is a constant, equal to approximately 3.1416 (the exact value is irrational), which is defined as the ratio of the circumference of any circle to its diameter (all circles are similar so the ratio is always the same).
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.
By using the other information supplied about the circle to calculate either its radius (from which its area can be calculated) or its area (if the circle is similar to another with a given area and some ratio between the two circle is given):If the diameter is given: radius = diameter ÷ 2If the circumference is given: radius = circumference ÷ 2πIf the circle is similar to another circle which has a given area, and the length ratio is given; square the length ratio to get the area ratio and apply to the given area.

diameter ------------- Diameter. The R (radius) of a circle multiplied by two equals the diameter.
Pi or 3.141592654
Radius of curvature divided by tube diameter. To get the radius of curvature, imaging the bend in the tube is a segment of a circle, the radius of curvature is the radius of that circle.
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.
