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

    A)  800                 

    B)  900

    C)  1000               

    D)  1200

    Correct Answer: C

    Solution :

    \[\because \] \[t=1.75cm\] \[\therefore \] Circumference of wheel\[=2\pi r\] \[=2\times \frac{22}{7}\times 1.75=11\] \[\therefore \] Number of revolutions \[=\frac{11000}{11}=1000\]
