Distance covered is the total distance travelled by the body. In two complete rounds total distance covered would be 2 cross times 2 straight pi open parentheses 2 straight R close parentheses equals 8 πR
Displacement is the shortest distance between starting point and end point. Here the body completed 2 rounds and hence starting and end point is same. Therefore displacement is zero.
