Question

a circle is cteredat O with its diameter 16cm . if OA=8cm , OB = 9cm , OC = 10cm ,OD =5cm and OE=17cm , classify A,B,C,D,E and its interior and exterior or on the circle.

Answer 1

Answer:

16 cm

Step-by-step explanation:

Given OA=10cm

OC=6cm

∠OCA= 90

∘

By Pythagoras theorem,

AC

=OA

−OC

AC=8cm

We know that perpendicular from centre of circle bisects the chord

Therefore AB=2AC

AB=16cm
