Distance travelled = 2πr(3/4) = 600π = 1884.955592
Displacement = √( 400² + 400² ) = 565.6854249
Displacement = √( 400² + 400² ) = 565.6854249

Answer:
Radus given = 400 m
Distance travelled = 2πr×(3/4) =2 × 22/7×400×3/4 = 1884.96m
ii)The displacement is the shortest path between A and B, i.e AB =√(〖AO〗^2+〖OB〗^2 )=√(〖400〗^2+〖400〗^2 )=565.69m
