you have a triangle formed by the radius on 2 and the chord on the other.
the angle in that triangle that is opposite the chord, find its measure in radians
take that measure (in radians) and multiply it by the radius to get the arc length

How do you find the radius of a circle if you know the length of a chord is 4 cm length?
Unless the chord is the diameter, there is no way to measure the radius of the circle. This is because the radius is in no way dependent on chord length since circles have infinite amount of chord lengths.
How do you find the chord length with the central angle and radius?
If the central angle is 70 and the radius is 8cm, how do you find out the chord lenght?
How do you find chord with known radius and degree?
Length of chord (assuming that is what you want) = 2*r*sin(x/2) where x is the measure of the angle subtended at the centre.
How do you find a chord length with the central angle and radius given?
If the radius is 8cm and the central angle is 70, how do yu workout the chord lenght?
How do you find radius of a circle if cord length is given?
The longest chord in a circle is its diameter and halve of this is its radius.

How do you Find Arc Length of Segment from Chord Length and Radius?
multiply the chord length and radius and divide by 2
How do you find the area of a circle without knowing the radius?
If the circumference or diameter is given then you can find the radius or simply measure the distance from the centre of the circle to the circumference.
Find the lenght of a chord that cuts off an arc of measure 60 degrees in a circle of radius 12?
The radial length equals the chord length at a central angle of 60 degrees.
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.
How do you find a chord length with the central angle and radius given?
If the radius is 8cm and the central angle is 70, how do yu workout the chord lenght?
What is the formula to calculate the radius of a segment knowing the height of the segment and cord length?
Assume that the height of the segment is h, the chord length is c and the radius is r then: r2=(r-h)2+(c/2)2 (We join two radii to the two ends of the chord then extend the height of the segment to the center of the circle in which the segment is inscribed so this height will bisect the chord and you use the pythagorean theorem to find the radius)
How do you find radius of a circle if cord length is given?
The longest chord in a circle is its diameter and halve of this is its radius.
How does he find the measure of a radius if he knows the measure of the diameter?
The radius of a circle is half the diameter.
