Answer:
d = 3 cm
Step-by-step explanation:
Given that,
The distance of a cord, c = 8 cm
The radius of the circle, r = 5 cm
Half of the cord = 4 cm
We need to find the distance of a cord from the centre of the circle. We can find it using Pythagoras theorem,
[tex]5^2=d^2+4^2\\\\d^2=25-16\\\\d=3\ cm[/tex]
So, the required distance is 3 cm.
