Question

In a circle of radius 17 cm, find the distance of a chord of length 16 cm from center.​

Answer 1

Answer:

Distance of chord from centre

$\sqrt{ {17}^{2} - {8}^{2} } \\ = \sqrt{ {15}^{2} } \\ = 15$

Answer 2

Answer:

15

Step-by-step explanation:

Radius = 17 cm

length of chord =16 cm

we know that a perpendicular drawn from a center of the circle bisect the chord .

so the length of half chord becomes 8cm

as per pathagorours therom

17^2 = 8^2 + the distance of chord form center ^2

distance of the chord from center =√17^2 - √8^2

= √289 - 64

= √225

= 15 cm
