    Answer: 5500cm.

    Step-by-step explanation:

    A revolution corresponds to circumference of the bicycle wheel.

    The radius of the circle = 70/2 since two radii makes a diameter.

    Therefore r = 35cm

    Circumference of a circle = 2πr or πd where π = 3.142 or 22/7

    We now have = 2 x 22/7 x 35

    Therefore 0ne revolution = 220cm.

    Therefore, the distance traveled by making 25 revolution

    = 220 x 25

    = 22000/4

    = 5500cm.
