Answer: (4) 4000
Explanation:-
The radius of a circular wheel = 1.75 m
Formula-
The circumference of a circular wheel = 2 x pai x r
Where, r = radius of the circle

Then, the distance covered by a circular in a round = 2 x 22 x 1.75/7
= 44 x . 25
= 11 meters
Total distance covered by circular wheel = 44 km
= 44 x 1000 m                                                  (1 km = 1000 m)
= 44000 m
The number of revolutions made by circular wheel = 44000/11
= 4000
Hence, the answer is (4) 4000.
