A) \[2\sqrt{2}\,\,cm\]
B) \[3\sqrt{2}\,\,cm\]
C) \[2\sqrt{3}\,\,cm\]
D) \[4\sqrt{2}\,\,cm\]
Correct Answer: D
Solution :
Here, OA = 10 cm, OB = 3 cm \[\therefore \] \[AB=\sqrt{{{3}^{2}}-{{1}^{2}}}=\sqrt{8}\,\,\text{cm}\] \[\therefore \] Required length \[=BC=2AB=2\sqrt{8}\,\,\text{cm}=4\sqrt{2}\,\,\text{cm}\]You need to login to perform this action.
