Question

Radius of circle is 15 cm. There are two chords of length 24 cm each . What will be the distance of these chords from the centre of the circle?​

Answer 1

Answer:

9cm

Step-by-step explanation:

L=length of chord

R=Radius of circle

h=Distance from center

$l = 2 \sqrt{ {r}^{2} - {h}^{2} }$

$24 = 2 \sqrt{ {15}^{2} - {h}^{2} }$

$24 = 2 \sqrt{225 - {h}^{2} }$

$\sqrt{225 - {h}^{2} } = 12$

$225 - {h}^{2} = 144$

${h}^{2} = 81$

$h = 9$

Hope u understand the solution, I have just used the basic Pythagoras theorem
