You can put this solution on YOUR website!
Assume it is:
A chord is 5cm from the center of a circle with a radius of 13 cm.
What is the length of the chord
:
If you draw this out, you can see that two right triangles are formed with one side being half the chord, the other 5 cm, the radius is the hypotenuse
a^2 + b^2 = c^2, where:
a = 5 cm
b = half the chord
c = 13
:
5^2 + b^2 = 13^2
b^2 = 169 - 25
b^2 = 144
b = sqrt%28144%29
b = 12 cm is half the chord
therefore
Chord = 24 cm
