0:5
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.
It depends on the ratio of what of the circle? Its circumference, diameter, area?
Length of diameter:length of radius = 2:1
diameter ------------- Diameter. The R (radius) of a circle multiplied by two equals the diameter.
The diameter of a circle is twice its radius
The radius of a circle is half the diameter so if the radius of a circle is r, then the diameter is 2r.
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.
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.
The diameter of a circle is twice its radius
