Wheel X with radius 5 makes 5 revolutions along a road, and wheel Y with radius 6 makes 4 revolutions along the same road. What is the difference in the distances traveled by the 2 wheels?

  • math -

    Circumference = 2πr

    Distance travelled by wheel X
    =5*2π(5)
    =50π
    Distance travelled by wheel Y
    =4*2π(6)
    =48π
    What is the difference?
