an object is travelling in a circular path of radius 21m metre calculate its distance and displacement after completing 5rounds
Answer:
4.2
Explanation:
21/5 = 4.2 is the answer
Verified answer
Answer:
given radius =21m
no. of round =5
now
circumference of the circle=2πr
=2x 22/7 x 21
=44x3
=132m
therefore ,distance=5x132cm
= 660cm
displacement=diameter of the circle
=2xradius
=2x21
=42cm
