Question

A man is walking on a circular track of radius 100m calculate the distance and displacement in (1) one complete round (2) half round
​

Answer 1

Answer:

Explanation:

for one complete round

the distance travelled =2πr=2×22/7×100=628m

displacement=zero

for half round

the distance =πr=3.14×100=314m

displacement=the diameter of the circle=2r=200m
