ANSWER:
We have a circle of radius 8.5 cm.
And Distance between the chord and center is
5 cm.
OB = 8.5 cm (radius)
OP = 5 cm
Here, OP is perpendicular to AB
So we have AB = 1/2 PB
Step-by-step explanation:
By pythagoras theorem
OB² = OP² + PB²
PB² = OB² – OP²
PB² = ( 8.5² – 5² ) cm
= 47.25 cm
PB = 6.8 cm (approx)
Now, chord of circle
= 6.8 × 2 cm
= 13.6 cm
