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...=)
radius = diameter/2
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.
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.
Radius is half the length from one side of a circle to the other or half the diameter.
(arc length / (radius * 2 * pi)) * 360 = angle
The approximate radius is five (5) inches.
That will depend on the length of the radius which has not been given but in general the circumference of a circle = 2*pi*radius or diameter*pi
A circle with a radius of 8 inches has a circumference of 50.27 inches.
radius = diameter/2
The radius of a circle with a circumference of 232.4 inches is 37 inches.
Radius is one-half of the diameter of a circle. Therefore, the radius of an eight-inch diameter circle is four inches. The diameter of a circle is a straight line joining a point on the circumference through the centre to the 'opposite' point on the circumference.
The radius of a circle is half of the diameter! So, if the diameter was four inches, the radius would be two inches!
The longest chord in a circle is its diameter and halve of this is its radius.
radius = 20/(2*pi) = 3.183098862 inches
The radius of a circle is half the length of its diameter. Therefore, if the diameter of a circle is 20 inches, the radius would be half of 20, which is 10 inches. The formula to find the radius of a circle is radius = diameter / 2. So in this case, the radius would be 10 inches.
Area = Pi(r)2 - A circle with a radius of 25 inches has an area of 1,963.5 square inches.
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.
