Question

A bicycle wheel with the diameter 70cm is making 25 revolutions while travelling. Find the distance covered by the bicycle

1 Answer

  • 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.
