Option 1: $16 \sqrt{3}$ cm
Option 2: $8 \sqrt{3}$ cm
Option 3: $12 \sqrt{3}$ cm
Option 4: $10 \sqrt{3}$ cm
Correct Answer: $16 \sqrt{3}$ cm
Solution : AD = DB Let, $O{_1}O{_2} = 2x$ Again $O{_1}A = O{_2}A = 2x$ [Radius of the circle] $\angle ADO{_1} = 90°$ $O{_1}D = O{_2}D = \frac{2x}{2} = x$ $AD = \frac{1}{2}AB = 12$ Using the Pythagorean theorem, We get, $AD^2 = AO{_1}^2 +O{_1}D^2
