Question

A
body moves around a circular path of radius 7m and completes half round.Find distance and displacement.Given:-π=22÷7​

Answer 1

Answer:

d = 22 m ,. s = 7m

Explanation:

distance = πr

= 22/7 × 7

= 22 m

displacement

= 2r

= 2×7

=14 m

Answer 2

well, first we need to find total distance

so we use formula '2πr'

= 2×22/7×7

= 44m

then half distance =44/2=22 m

displacement is the shortest distance between two points and that is diameter'

diameter=2×r

=2×7=14

so displacement=14m
