    What will be the area of a circle whose perimeter is 88 cm?

    A)  576 \[c{{m}^{2}}\]          

    B)  616 \[c{{m}^{2}}\]

    C)  636 \[c{{m}^{2}}\]       

    D)  Cannot be determined

    Correct Answer: B

    Solution :

                    Let the radius of circle be r cm. \[\therefore \]  \[2\pi r=88=r=\frac{88\times 7}{2\times 22}=14\,cm\] \[\therefore \]  \[\text{Area}=\pi {{r}^{2}}=\frac{22}{7}\times 14\times 14=616\,c{{m}^{2}}\]
