Question : In the following figure, two circles touch each other externally. The radius of the first circle with centre P is 25 cm. The radius of the second circle with centre Q is 4 cm. Find the length of their direct common tangent, AB. The figure is not to scale and is only for representational purposes.
Option 1: 21 cm
Option 2: 18 cm
Option 3: 20 cm
Option 4: 22 cm
Correct Answer: 20 cm
Solution : Here, $r_{1} = 25, r_{2} = 4$ Length of a common tangent = $\sqrt{(r_{1}+r_{2})^{2} - (r_{1}-r_{2})^{2}}$ = $\sqrt{29^{2} - 21^{2}}$ = $\sqrt{841-441}$ = $\sqrt{400}$ = $20$ cm Hence, the correct answer is 20 cm.
