5000 revolutions covering 22 kilometers.
This means circumference * 5000 revolutions = 22 km
2πr*5000=22*1000m
44/7*r*5000= 22000 m
r = 22000*7/44*5000
r = 0.7 m
r = 70 cm
Hope this helped u.

Given total no of revolutions= 5000
           Distance covered =22 Kms
            ∴
 Circumference *total no of revolutions=distance covered
             2*22/7*r*5000=22*1000
             44/7*r*5000=22000
               r=22000*7/44*5000
               r=0.7m
∴r=70cms
