  • Question
  • The diameter of a wheel is 63 cms. Distance travelled by the wheel in 100 revolutions is?


  • Options
  • A. 99 meters
  • B. 198 meters
  • C. 63 meters
  • D. 136 meters

  • Correct Answer
  • 198 meters 

    Explanation

    Distance travelled in 1 revolution = circumference of the wheel
    = ?d
    = ( 22/7 ) x 63
    = 198 cm

    So the distance travelled in 100 revolutions = 100 x distance travelled in 1 revolution
    = 100 x 198 cm
    = 19800 cm
    = 198 m
