Question

The distance of a chord from centre of a circle of radius 17cm is 8 cm. find the length of the chord

Answer 1

Answer:

hay I think this is your answer

Step-by-step explanation:

Let AB be the chord with distance from the center =8 cm

OA=radius=17cm

Now, OC⊥AB

Then, AC=CB=2AB.......(i)....(perpendicular drawn from the centre of the circle to the chord bisects the chord)

Now, △ACO is right angled triangle at C

∴AC=(OA2−OC2)=(172−82)=(225)=15cm

Hence, AB=2×15=30cm ............ From (i)
