If you are referring to the diameter(the distance across the circle or the length of the longest line segment that is passing through the center of the circle), then the answer will be 12 in, since that the diameter is twice the length of the radius. But if you are talking about the circunference, you could use the formula C=2pi(r) or C=pi(d). Thus the answer will be 37.68 in. Please be more specific next time you ask...=)

How do you find the length of a radius of a circle?
radius = diameter/2
What is the radius of a 60 inch diameter circle?
The radius of a circle is half of its diameter. Therefore, if the diameter of the circle is 60 inches, the radius would be half of 60, which is 30 inches. The formula to find the radius from the diameter is: radius = diameter / 2.
How do you find the radius given the chord length?
If you are given a chord length of a circle, unless you are given more information about the chord, you can not determine what the radius of the circle will be. This is because the chord length in a circle can vary from a length of (essentially) 0, up to a length of double the radius (the diameter). The best you can say about the radius if given the chord length, is that the length of the radius is at least as long has half half the chord length.
Where can you find the radius?
Radius is half the length from one side of a circle to the other or half the diameter.
How do you find the central angle of a circle if I am given the arc length and radius?
(arc length / (radius * 2 * pi)) * 360 = angle
