A person is moving along a circular path of radius 7m for 5 minutes.Find distance covered and displacement of the person after 5 min if he completes one round in 60 sec

2
CIRCUMFERENCE=2 (PIE)R
SO,44M=2*22 BY 7*7
1 MIN IS TAKEN FOR 1 ROUND AND THE COVERED IN FIVE MINS=220M(44*5)
DISPLACMENT=0M BECAUSE THE PERSON REACHES THE SAME POINT FROM WHERE HE STARTED AFTER 5 MINUTES.
HOPE U UNDERSTAND.

Circmference of a circle=2πr
2*22/7*7=44m
1 round=1min
dist. covered in 5 min=44*5=220m
displacement=0m as he reaches the same point where he started after 5 mins

R= 7m Circumference= 2πr=2π7=44m 60s=1min In 1 min the person completes 1 round In 5 min the person completes 5 rounds Distance covered= 5×44=220m Displacement= 0 m ( after completing 5 rounds the person would come to the starting point)
