    The radius of circular wheel is 1.75 cm. The number of revolutions it will make in travelling 11 km is \[\left( use\,\,\pi =\frac{22}{7} \right)\]

    A)  800                             

    B)  900

    C)  1000   

    D)  1200

    Correct Answer: C

    Solution :

    \[r=1.75\,m\] \[\therefore \] Circumference of wheel \[=2\pi r\]                                        \[=2\times \frac{22}{7}\times 1.25\]                                        \[=11\] \[\therefore \] Number of revolutions \[=\frac{11000}{11}\]                                      \[=1000\]
