    The diameter of a wheel is\[\text{1}.\text{26 m}\]. How far will it travel in 500 revolutions?

    A) \[\text{267}0\,\text{m}\]

    B) \[\text{288}0\text{ m}\]

    C) \[\text{198}0\text{ m}\]

    D) \[\text{1596}\,\text{m}\]

    Correct Answer: C

    Solution :

    [c] Radius of the wheel \[=\frac{126}{2}=0.63m\]
    Distance travelled in one revolution
    \[=2\pi r=2\times \frac{22}{7}\times 0.63=3.96m\]
    \[\therefore \]   Distance travelled in 500 revolutions
    \[=500\times 3.96=1980\,m\]
