The radius is a cord, is it not?
The longest chord in a circle is its diameter and halve of this is its radius.
-- 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.
s=arc lengthr=radiusAnswer: (r^2).(asin(s/(2r))-(s/16).sqrt(4r^2-s^2)
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
The radius is a cord, is it not?
The longest chord in a circle is its diameter and halve of this is its radius.
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)
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"

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.

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
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.
The Norelco Reflex 7310 XL shaver is a cordless razor,so the cord has zero length.
