The answer depends on what information you have about the circles and their relative positions. If you have the radii of the two circles, r and s, and the distance between their centres, d then the two circles can be written as:(x + d/2)2 + y2 = r2 and (x - d/2)2 + y2 = s2.
=> 2xd = r2 - s2
=> x = (r2 - s2)/2d where all three values on the right hand side are known. So, x can be calculated and, substituting this value of x in the equation for either circle gives a quadratic equation in y. Solving the quadratic will give y1 and y2. Then the coordinates of the chord's end-points are (x, y1) and (x, y2) and the length of the chord is abs(y2 - y1).
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.
If the central angle is 70 and the radius is 8cm, how do you find out the chord lenght?
The length of a chord = pi*r*x/180 where x is the angle subtended. = pi*5*80/180 = 6.98 cm
If the radius is 8cm and the central angle is 70, how do yu workout the chord lenght?
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

multiply the chord length and radius and divide by 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.
If the central angle is 70 and the radius is 8cm, how do you find out the chord lenght?
There are a couple of different ways of finding the length of the chord of a circle. Probably the best is what is called the half angle formula.
The length of a chord = pi*r*x/180 where x is the angle subtended. = pi*5*80/180 = 6.98 cm
If the radius is 8cm and the central angle is 70, how do yu workout the chord lenght?
The radial length equals the chord length at a central angle of 60 degrees.
r = known radius x = known arc length --------------------------- C (circumference of circle) = 2 * PI * r A (angle of chord in degrees) = x / C * 360 L (length of chord) = r * sin(A/2) * 2
It'll be the largest chord of the circle.
well,first the radius is half of the chord. Radius is the distance from the circle centre to the chord end. The chord is the line joining the ends of the arc. Draw this line. Call the distance from the arc of the circle at its deepest point to the mid point of the chord "c". If extended, this line will go throught the centre of the circle. Call half the length of the chord "y". Then the properties of circles and chords is that c(d-c)=y2 where d is the circle diameter, so that d = y2/c + c. And then radius is half that.
