    Find the area of all quadrant given in the figure.

    A) \[190\,c{{m}^{2}}\]

    B) \[198.14\,c{{m}^{2}}\]

    C) \[201.14\,c{{m}^{2}}\]

    D) \[222.14\,c{{m}^{2}}\]

    Correct Answer: C

    Solution :

    In the figure, we have 4-quadrants of radius \[8cm\]         
    \[\therefore \] Area of all quadrants \[=4\times \frac{1}{4}\pi {{r}^{2}}=\pi {{r}^{2}}\]
    \[=\frac{22}{7}\times 8\times 8=201.14c{{m}^{2}}\]
    So, option [c] is correct.
