Question

the road roller makes 5000 revolutions in covering 22 km find the radius of the roller​

Answer 1

Answer:

n*(2[*tex] \pi [/tex]*radius)=total distance covered (eq 1), where n is the no of revolutions

In this problem:

n=5000

total distance covered= 22km or 22000m or 2200000 cm

from (eq1), we have: radius=2200000/5000*2*\piπ

therefore radius=70.028 cm

Answer 2

Answer is that
