    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.
