Question

Radius of a circle is 34cm and the distance of the chord

from the centre is 30m, find the length of the chord.​

Answer 1

Step-by-step explanation:

let the chord be AB

O be the center of the circle.

OC be the perpendicular from the centre of the circle to the chord AB.

[The perpendicular drawn from the centre of the circle to the chord bisect the circle.]

so, OC perpendicular AB

${oc}^{2} + {ab}^{2} = {oa}^{2} \\ {30}^{2} + {ac}^{2} = {34}^{2} \\ 900 + {ac}^{2} = 1156 \\ {ac}^{2} = 1156 - 900 \\ {ac}^{2} = 256 \\ ac = \sqrt{256} \\ ac = 16 \\ \\ therefore \: ab = 2 \times 16 = 32 \\ \\ \\ hope \: it \: helps \: you \\ thank \: you$
