It is usually simpler to measure it. If you really want to CALCULATE it, the calculation (and whether you can calculate it at all) depends on what other information is available.

What is the formula to calculate the length of a chord given the included angle and radius?
the length is: 2rsin(1/2 theta) where r is the radius and theta is the included angle.
What is the relation between radius and chord length of circle?
This requires trigonometry If theta is the angle from the center of the circle to the edges of the chord, then chord length = 2Rsin (theta/2)
What is a line segment that has both endpoints on the circle?
This is referred to as a chord. If the chord passes through the center of the circle, it represents the diameteror width of the circle.For a circle, the length of the diameter is the longest possible length of a chord.
How do you find the length of the chord of a circle?
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.
Formula of radious given curve length and chord length?
R = radius c = chord length s = curve length c = 2Rsin(s/2R) you can solve for radius by trial and error as this is a transcendental equation
How do you calculate the coordinates of chord given the length of radius and chord?
You cannot. If you rotate the circle around its centre, the lengths of the radius and chord will remain the same but the coordinates of the chord will change.
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 can I calculate cord length using arc length and radius?
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
What is the formula to calculate the length of a chord given the included angle and radius?
the length is: 2rsin(1/2 theta) where r is the radius and theta is the included angle.
What is the formula for calculating the central angle given chord length and radius?
You can use the cosine rule to calculate the central angle.
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 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.
In a circle whose diameter is 20in and a chord is 6in from the center what is the length of the chord?
the chord is 4in long
What is the relation between radius and chord length of circle?
This requires trigonometry If theta is the angle from the center of the circle to the edges of the chord, then chord length = 2Rsin (theta/2)
How do you calculate developed length of sheet metal forming?
ON the cad offset the bend radius from the internal radius of the sheet metal part by 40% of the total sheet thickness,and measure the chord length of the radius. that will be the developed length.
What is the diameter of a circle?
A chord of a circle is a straight line that joins any two points on the circumference of a circle. The diameter of a circle is the length of the chord that passes through the centre of the circle; it is the chord of longest length and is twice the radius of the circle in length.
A chord of a circle of radius 5cm subtends the length of 80 degree at the center of the circle find the length of the chord?
The length of a chord = pi*r*x/180 where x is the angle subtended. = pi*5*80/180 = 6.98 cm
