The diameter is twice the radius (always). So the diameter will be 22.
If the measurement of eleven millimeters refers to the diameter of the circle, then the radius would be half of that, which is 5.5 millimeters. If the eleven millimeters is already the radius, then it remains 11 millimeters. Please clarify if you meant diameter or radius for a precise answer.
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.
The diameter of a circle is twice its radius
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.
The radius of a circle is half the diameter, so the radius of a 6 inch diameter circle is 3 in.
The radius of a circle is half of its diameter
The radius of a circle is half of its diameter.
The diameter of a circle is twice its radius.
The diameter of a circle is twice its radius.
The Radius of a circle is half the Diameter of the circle.
