Answer:
13.1999 km
Step-by-step explanation:
Diameter = 60cm
Radius = 30
Circumference of Cylinder = 2πr
= 2 × 22/7 × 30
= 1320/2
= 660cm ^2
so one revolution take 660cm ^2
700 times rotating takes = 660× 700
= 462,000cm^2
1m = 1000cm
462000 = 462000/1000
= 462 m
in 1 minutes it takes 462 m
then in 10 minutes = 462 × 10
= 4620 m
= 4620/1000
= 4.62 km
hope this helps you
