Basically, this item is asking for the circumference of the circular base and multiply the circumference by 8. 
That is,
                            distance rolled = 8(πD)
Substituting the known values,
                            distance rolled = 8(π)(22 inches)
                             distance rolled = 176π inches 
                                                   ≈ 552.92 inches
