Question

a cord of length 8 cm is drawn in a circle of radius 5cm calculate its distence from the cenrmter of circle​

Answer 1

Answer:

3 cm

Step-by-step explanation:

Let AB =8 cm. be the chord of the circle with radius AO=5 cm.

Draw OP⊥AB.join OA

according to the theorem

AP=21AB=21×8=4cm.

In △APO,∠A=90∘

∴(AO)2=(AP)2+(OP)2

OP=(AO)2−(AP)2

⇒52−42

⇒9

⇒OP=3cm
