    The circumference of a circle is 44 m; then the area of the circle is

    A)  \[6084.5\,{{m}^{2}}\]       

    B)  \[276.5\,{{m}^{2}}\]

    C)  \[154\,{{m}^{2}}\]          

    D)  \[44\,{{m}^{2}}\]

    Correct Answer: C

    Solution :

         \[2\pi r=44\] \[r=\frac{44}{2\times \frac{22}{7}}=7\,m\] Area of a circle\[=\pi {{r}^{2}}=\frac{22}{7}\times 7\times 7\] \[=154\,{{m}^{2}}\]
