Question : Observe the given figure. The distance between the two centres AB is:
Option 1: 10 cm
Option 2: 11 cm
Option 3: 13 cm
Option 4: 12 cm
Correct Answer: 13 cm
Solution : Construction: Draw a perpendicular from $A$ to $E$. Since OC and OD are tangents, $\angle ACD$ = $\angle BDC = 90^\circ$ $AEDC$ forms a rectangle. Applying Pythagoras theorem in $\triangle AEB$, $AB^2 = AE^2+EB^2$ ⇒ $AB^2 = CD^2+(BD-DE)^2$ ⇒ $AB = \sqrt{(8-3)^2+12^2}$ ⇒ $AB=\sqrt{25+144}$
