The circumference is calculated through the equation,
                                C = 2πr
where C is circumference and r is radius.

Earth: 
                            C = 2π(6371 km)
                                = 40030.17 km

Moon:
                            C = 2π(1737.5 km)
                               = 10917.03 km
The difference between the two circumferences is approximately 29113.13 km.
