96 cm

as
if Cis the length of the cord &r is the radius &L is the distance from the center
r^2-L^2 =(C/2)^2
(C/2)^2 =50^2-14^2 =2304
c/2=48
c=96cm

The cord is 14 cm from the center. The radius is 50cm

There for you have a right triangle with a hypotenuse of 50cm
and a side of 14 cm.

c^2=A^2+b^2

50^2=14^2+b^2
2500=196 +b^2
b^2= 2304
b= 48

b is 1/2 of the length of the cord.

the cord is 96 cm in length

Draw a radius, which bisects a chord 14 cm from the centre.
Draw radii to each end of the chord, let x represent 1/2 length.
By Pythagoras, 50^2 = 14^2 + x^2
2500= 196+x^2
x= sqrt(2500-196)
x = sqrt(2304)
x=48
Chord is 96 cm

since the radius of the circle is 50cm and the chord is 14cm from the center each half of the chord can be considered one of the legs of a right triangle. thus through the pythagorean theorem one would get d=sqrt(50^2-14^2), where d is half of the chord. so ch=2d=2*sqrt(2500-196)=2*sqrt2304=2*48=96cm

Draw a chord through a circle.
Draw a radius.
From the center, draw a perpendicular bisector to the chord.
Chord breaks down to 7 cm.
With radius of 50, do a pathagorean formula.
50^2 - 7^2 = y^2
what is the answer?

[04]
Let the kebgth of half the chord be c
Therefore C^2+14^2=50^2
c^2=50^2-14^2
=2500-196
=2304
c=48 cm
Therefore length of the chord is 2*48 or 96 cm
