distance is the actual path length between final and initial point so
The distance covered is half the circumference means 2πr/2 or πr
but the displacement is the minimum shortest path which is a straight line in this case the diameter or 2r
ratio= πr/2r
π/r

DISPLACEMENT: 2×radius = 2r
THEREFORE RATIO = πr : 2r
