The answer is 9
9 mm
Diameter = 2 x radius = 18 mm .
Diameter of circle = 2 * Radius of the circle.
Since diameter is twice its radius, the radius of this circle would be 60
The radius (radii) of a circle is 1/2 of the diameter. The radius of a circle with a 6.2 cm diameter is 3.1 cm.
If the radius of a circle is 18mm, its diameter is: 36mm
9mm
9 mm
Diameter = 2 x radius = 18 mm .
254.47 square mm
18mm or 1.8 cm
The radius of any circle is its diameter divided in half. So: 18mm/2 = a radius of 9mm
The diameter is twice the radius. Or The Radius is half the diameter. Algebraically, d = 2r or r = d/2
The radius of a circle is half the diameter so if the radius of a circle is r, then the diameter is 2r.
Irrespective of the units of length, be they Metric, or Imperial , the diameter is twice the radius. Algebraically written as d = 2r o r ( d = r + r).
The radius of a circle is always half of the diameter. If the diameter is 85.4, the radius is 42.7.
The radius of a circle is half of the diameter, so the radius of a circle with a diameter of 14in is 7in.
