Answer 1

Answer:

Radius (R) = 5 cm

Step-by-step explanation:

We can see that the ∆AOB is a right angled triangle.

So, applying Pythagoras Theorem,

AB² + OB² = AO²

But, OB = Radius, AB = 12 cm, AO = 13 cm

Let OB (Radius) be R.

So,

$= > {R}^{2} + {12}^{2} = {13}^{2}$

$= > {R}^{2} = {13}^{2} - {12}^{2}$

$= > {R}^{2} = 169 - 144$

$= > {R}^{2} = 25$

$= > R = 5 \: cm$
