kriti`s question answer is

as the man covers the path displacement is 0 because after he travels the path he again come back to the same place
and the distance covered by him is 62m as 10 multiplied to 10 =20 thats diameter and then multiplied to 3.14
thats come across to 62 meters.

another ouestion………..

A bullet is fired from a rifle with a horizontal velocity of 500 feet per second from a height of 16feet at the same time, another bullet falls out of the gun. without obstruction, which bullet will reach the ground first? how long will it take? At what velocity will it hit?
