Question

the length of one chord of a circle of radius 13 cm is 10 cm find the distance of Chord from the centre of the circle​

Answer 1

Answer:

12cm

Step-by-step explanation:

since perpendicular from centre to chord bisects it , so half of chord=10/2=5cm

Now , using Pythagoras theorem in formed triangle

we get distance of chord =

=$\sqrt{(13) { }^{2} - 5 {}^{2} }$

$\sqrt{169 - 25}$

$\sqrt{144}$

=12cm

Please give it 5 stars☺☺☺☺☺
