a bicycle wheel has a diameter of 40 cm how many revolutions would a wheel make if the bike travels 1 km pi=3.14 (answer please
with working out)
1 answer:
<span>Circumference of a circle = Diameter × pi
Circumference of a circle = 40 cm × 3.14
<u>Circumference of the wheel = 125.6 cm
</u>
1 Km = 1000m
</span>Circumference of the wheel × 1000m = The number of revolutions
125.6 × 1000m = 125600
<u><em>
</em></u>The wheel would make <u>125600 revolutions</u> if the bike travels 1 km.
