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

If given the length of arc and the radius how do you figure the straight line cord?
The radius is a cord, is it not?
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 calculate the length of a cord of a circle?
-- Take the information you're given, such as, for example, the circle's radius or diameter, and the distance from the center of the circle to the chord's midpoint. -- Jot down a few things you know about circles and right triangles, such as the relationship between the radius, diameter, and circumference of a circle, and the Pythagorean Theorem. -- Use what you're given, combined with what you know from your studies and your general knowledge, to calculate what is required.
What is the area of an arch with given radius and cord length?
s=arc lengthr=radiusAnswer: (r^2).(asin(s/(2r))-(s/16).sqrt(4r^2-s^2)
How do you get radius given the versine and length of cord?
Chord constant = ((A x B)/2)x1000 Radius = chord constant/versine So a 10m chord versine measured at 5m: ((5x5)/2)x1000 = CC 12.5x1000= 12500 CC/V = r 12500/30 = 416

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.
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)
What is the formula to calculate the height of a cord?
Easiest way to find the length of a cord: (enter in scientific calculator as shown below) x=2 squareroot(h(2*r-h)) Where: x is the answer or the endpoint of the cord where it would meet the radius. h is height or the amount of flat you want from the top of the radius. r is the radius. So: Say we have a round bar which is 90mm radius (180mm diameter). We want to machine a flat on the bar 40mm deep from the outer edge but need to know the distance where the edge of the flat meets the radius. x=2 squareroot(40(2*90-40)) x=74.833mm This calculation is useful to find any point at which the cord will intersect the radius/diameter. -------------------------------------------------------------------------------------------------------------- You mean the highest point in the segment formed by a cord, or, how much do you shave off a circle to get a flat of a known length? R = circle radius r = 1/2 cord length H = height of segment Square 'r', or multiply 'r' by itself Square 'R' and subtract value of your 'r squared' Find 'square root' of this remainder. Use calculator key or test multiply to find a close factor. Subtract this factor from "R" and the result is "H"

What is the length of spermatic cord?
7cm
Is it harmful to plug an extension cord into another on identical to it?
Not in general. You can buy extension cords in a variety of lengths. However, the longer the cord the more the resistance and the bigger the voltage drop across the length of the cord. If you were using the cord outdoors and the junction was on the ground it is possible for moisture to cause a short at the junction.
What is the normal length of umbilical cord?
Normal length of an umbilical cord can range from a couple feet in length to less than one foot, it all depends on the particular pregnancy.
What is spinal cord length?
45 cm
How do you get radius given the versine and length of cord?
Chord constant = ((A x B)/2)x1000 Radius = chord constant/versine So a 10m chord versine measured at 5m: ((5x5)/2)x1000 = CC 12.5x1000= 12500 CC/V = r 12500/30 = 416
What the max distance for a seow power supply cord for a portable machine?
There are three factors that come into play here. One is what is the amperage of the load. The other is the distance or length you want to be from the portable machine and the size of the wire in the cord. Without these values I can not calculate the voltage drop.
