Question

a chord 12 cm is 8 cm away from centre what is the length of the chord which is 6 cm away from center

Answer 1

we can solve this question by proportion method:
according to given question
$\frac{8}{6} = \frac{12}{x}$
now by cross multiplication method
$8x = 12 \times 6 \\ x = \frac{72}{8 } \\ x = 9$
hence the length of the chord is 9 cm
hope you got it
