Charlie is riding on his unicycle. If the unicycle's wheel has a radius of 9 inches and makes 2 revolutions every 3 seconds, what is the unicycle's speed in inches per second?

 

-Thank you

In 3 seconds, the distance that the unicycle travels =

 

2 revs * distance traveled per rev  =

 

2   * 2pi (9)  =  36 pi   inches

 

So...in 1 second  it travels  1/3 of this =    36 pi / 3    =   12 pi inches / sec ≈ 37.7 inches / sec
