    The wheel of a motor car makes 1000 revolutions in moving 440 m. The diameter (in metre) of the wheel is

    A) 0.44                             

    B) 0.14

    C) 0.24                             

    D) 0.34

    Correct Answer: B

    Solution :

    Distance covered by wheel in one revolution = Circumference of wheel \[\therefore \] \[\pi \times \text{diameter}=\frac{440}{1000}\] \[\Rightarrow \] \[\frac{22}{7}\times \text{diameter}=\frac{440}{1000}\] \[\Rightarrow \]   Diameter \[=\frac{440}{1000}\times \frac{7}{22}=0.14\,cm\]
