Answer 1

Answer:

The radius of the circle is 5cm. It is the right answer.

Answer 2

Answer:

radius of the circle is 5cm

Step-by-step explanation:

1. length of tangent=12cm
2. distance of p from centre is 13cm
3. let radius = x
4. by Pythagoras therom we get
5. 13^2=12^3+x^2
6. 169=144+x^2
7. 169-144=x^2
8. x^2=25
9. x=√25
10. therefore x= 5cm
