What is the radius of a circle in which the longest chord has length y?
Wiki User
∙ 13y ago
longest chord = diameter
y = longest chord
y = diameter
radius = 1/2 diameter
therefore, radius = 1/2y

A chord of a circle has length 4.2 cm and is 8 cm from the center of the circle what is the radius of the circle?
8.94
What is the length of a biggest chord of a circle radius 4 cm?
It is 8 cm
What is the longest chord that can be drawn on a circle?
The diameter (across the widest part) is the longest chord that can be drawn on a circle.
How do you Find Arc Length of Segment from Chord Length and Radius?
multiply the chord length and radius and divide by 2
A radius of a circle is perpendicular to a chord if and only if?
Bisects that chord
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 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.
Circle A has a radius of 3 m What is the length of the longest chord in circle A?
A chord of a circle is a line segment whose two endpoints lie on the circle. The diameter, passing through the circle's centre, is the largest chord in a circle. So the answer is 6 m
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.
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
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 the length of a biggest chord of a circle of radius 4cm?
It is the diameter which is twice the radius giving a length of 8 cm
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 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.
If a radius of a circle intersects a chord then it bisects that chord?
If radius of a circle intersects a chord then it bisects the chord only if radius is perpendicular to the chord.
A chord of a circle has length 4.2 cm and is 8 cm from the center of the circle what is the radius of the circle?
8.94
