    The radius of a wheel is 21 cm. How many revolution will it make in traveling 924 m? \[\left( Use\,\pi =\frac{22}{7} \right)\]

    A)  7                                

    B)  11

    C)  200                             

    D)  700

    Correct Answer: D

    Solution :

    Circumference of wheel \[=2\pi r\] \[=2\times \frac{22}{7}\times 21\,cm\] \[=132\,cm\] \[\therefore \] Number of revolution \[=\frac{92400}{132}=700\]
