Question

5. In the figure, 'O' is the centre of the circle.
OM = 3cm and AB = 8cm. Find the radius of
the circle
Le fimm
is the centre of the circle​

Answer 1

Answer:

OM= 3 cm , AB= 8 cm

AM= 4 cm

Join OA

In triangle OAM

by Pythagoras theorems

OA²=AM²+OM²

= 4²+3²

= 16+9

= 25

OA= 5 cm

the radius of circle is 5cm

Answer 2

Answer:

By Pythagoras theorem in tri.OMB,

OB=√[9+16]

So radius will be 5 cm.
