Answer 1

Answer:

[ PR = RQ ] = 1/2 PQ { perpendicular from the centre to the chord bisects the chord }

In ∆ PRO ,

since <R = 90° it is a right angled triangle so we can use Pythagoras theorem ..,,

PR² = PO² - OR²

PR² = 5² - 4²

PR² = 25 - 16

PR² = 9

PR = √9

=> PR = 3cm <=

Since ,,,

PQ = PR+RQ

( Since PR = RQ = 3 cm )...

PQ = PR+PR

PQ = 2PR

=> PQ = 2(3)

=> PQ = 6 cm <=
