Question

plz help answer all ASAP ​

Answer 1

Step-by-step explanation:

I am representing root as *

A. T. Q

22/7 R²= 2×22/7 r²

R²=2×3×3

So, R =3 * 2

In triangle, AOC

OA ² = OC ² +AC ²

(3*2)²=3²+AC²

18-9 =AC²

So, 9=AC²

Then, 3=AC

AC =BC=3 (as perpendicular divides chord in equal parts)

AB = AC +BC =3+3=6

SO, AB =6 cm
