Diameter = 5m
radius = 2.5m
distance in 1 revolution = 2 (pi) r = 2 * 22/7 * 2.5
distance in 3 revolutions = 3* 22/7* 2* 2.5 (we could take the value of 22/7 as 3.14)
                                  = 3* 3.14* 5 = 9.42* 5 = 47.10   
as the body comes back to the same position the displacement is 0
