A rhombus cannot be a cyclic quadrilateral because its opposite angles are not supplementary (unless it is a square). It cannot, therefore, have a radius.
A rhombus is a flexible shape which can range from almost a square to a very narrow shape. A rhombus with sides of x cm can contain a circle with any radius less than x/2 cm. The information in the question is insufficient to determine the radius. And a ratio requires some characteristic of the inscribed circle to be compared to an analogous characteristic of another shape.
The answer depends on what information about the rhombus you do have.
To find the circumference of a circle in rhombus you eat SH*t .

To find the value of x in a rhombus, use these properties. All sides of a rhombus are the same length. Opposite angles of a rhombus are the same size and measure. Intersection of the diagonals of a rhombus form right angles. Sides are perpendicular. The diagonals of rhombus bisect each other. Adjacent angles add up to 180 degrees.
Divide the circumference by 2PI to find the radius. ( C = 2PI*Radius)
you double the radius to find the diameter.
with a protractor
squares do not have a radius
A kite does not have a radius.
You already know the radius.
circumference = pi * 2radius (diameter) so to find radius you use circumference/(2 x pi) this will find radius ----
