Question : A and B are centres of two circles of radii 11 cm and 6 cm, respectively. PQ is a direct common tangent to the circles. If AB = 13 cm, then the length of PQ will be:
Option 1: 8.5 cm
Option 2: 13 cm
Option 3: 12 cm
Option 4: 17 cm
Correct Answer: 12 cm
Solution : Length of direct common tangent $PQ = \sqrt{AB^2-(r_1-r_2)^2}$ $= \sqrt{13^2-(11-6)^2}$ $= \sqrt{13^2-5^2}$ $= \sqrt{169-25}$ $= \sqrt{144}$ $=12$ cm Hence, the correct answer is 12 cm.
