Question

Diameter of a bicycle is 70cm. How many revolutions will it take to cover 44 m

Answer 1

$circumference=pi×d=pi×70</p><p>=22/7×70=220cm=2.20m</p><p>therefore number of revolutions required to cover 44m=44/2.20=20$

Answer 2

Answer:20

Step-by-step explanation:

So as the diameter of a circle is 70 CM then r = 35 CM.

Then circumference = 220 CM ( perimeter of circumstances = 2pir )

Distance to cover is 44m = 4400 CM (1m =100cm)

Total revolutions = 4400cm/ 220cm

= 20cm
