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?

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