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.


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.


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.


Is it possible for a chord of a circle to be the length as the diameter of that same circle?

Absolutely! As long as the chord goes through the center of the circle.


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 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.


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


Is a point the chord of a circle?

No, it is not. A chord is a line segment. It cannot have a length of zero. A point has no dimensions. The chord of a circle is a line segment that has its endpoints (both of them) on the curve (or circumference) of the circle.


What is the relationship between the chord and the radius of circle?

The relationship between the chord and the radius of the circle is Length of the chord = 2r sin(c/2) where r = radius of the circle and c = angle subtended at the center by the chord


Which best describes the diameter of a circle?

The length of a chord that contains the center of the circle


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
