    Three congruent circles each of radius 4 cm touch one another. What is the area (in \[c{{m}^{2}}\]) of the portion included between them?

    A)  \[8\pi \]                        

    B)  \[16\sqrt{3}-8\pi \]

    C)  \[16\sqrt{3}-4\pi \]        

    D)  \[16\sqrt{3}-2\pi \]

    Correct Answer: B

    Solution :

    The area of bounded portion\[=\left( \sqrt{3}-\frac{\pi }{2} \right){{r}^{2}}=\left( \sqrt{3}-\frac{\pi }{2} \right){{4}^{2}}=\mathbf{16}\,\sqrt{\mathbf{3}}\mathbf{-8}\pi \]
