Question

A chord of length 30 cm is drawn in a circle of radius 17 cm.
Find its distance from the centre of the circle​

Answer 1

Step-by-step explanation:

circle of radius 17 cm and chord 30 cm forms an isoceles triangle the distance from centre to chord divides the chord into half so the remaining triangle gives right angle traingle ,let distance be x

${17}^{2} = x {}^{2} + 15 {}^{2}$

$17 {}^{2} - 15 {}^{2} = x {}^{2}$

$64 = x {}^{2}$

$x = 8$
