Radius = 0.25 m
Circumference of the wheel = 2πr
= 2 × 3.14 × 0.25
= 2 × 22/7 × 0.25
= 44/7 × 0.25
= 11/7
Total distance = 11 km = 11000 m
No.of revolutions = 11000 × 11/7
= 11000 × 7/11
= 7000

Answer:
7000
Step-by-step explanation:
Radius of the wheel= 0.25 cm
Circumference= 2 πr
= 2*22/7*0.25
=11/7
Total distance= 11 km = 11000 m
Number of revolution=11000/11*7
= 7000
