If you mean ratio then I don't quite understand the question.. but if you mean RADIUS Then you take the diameter and divide it by two.
==============================================
There's no such thing as the ratio of circles. You can find the ratio of their diameters,
the ratio of their radiussesses, and the ratio of their areas.
-- The ratio of their diameters is: One diameter divided by the other one.
-- The ratio of their radiusses is the same number as the ratio of their diameters.
-- The ratio of their areas is the square of that same number.
To create three different drawings showing a number of circles and triangles in which the ratio is 2:3 you can: Start with an equilateral triangle, draw a circle inside it, draw an equilateral triangle inside the circle, draw a circle in the triangle and then draw an equilateral tiangle in the smallest circle. Or, you could draw 3 triangles and 2 circles in a line. Or, you could draw 3 triangles on a line with 2 circles between them.
If the ratio is 2 : 7 then the volumes are in the ratio 8 : 343.
diameter ------------- Diameter. The R (radius) of a circle multiplied by two equals the diameter.
You join the centres of the two circles. Divide this line in the ratio of the two radii. Draw the tangent from this point to either circle and extend it to touch the other circle.

The ratio of the diameters are the cube root of the ratio of the volumes. Therefore the diameter ratio is 3 to 5. 33 = 27 53 = 125
It is: 2 to 1
It is the ratio of their diameters.
It is the ratio of their diameters.
The ratio of 2 circles and 3 triangles can be expressed as : 2 : 3.
4/(7) = 4/7 is the ratio of circles to triangles. Some prefer to express this as 4:7.
The ratio of 2 circles and 3 triangles can be expressed as : 2 : 3.
Their given! You found it! Boom
Their radii, diameters or circumferences - in all three cases the ratio between the axle and wheel are the same.
It is 4/1.
It is: circumference/diameter = pi
Their circumferences are in the same ratio as their diameters.
