Question

Each wheel of bicycle has a radius of 70 cm. How many complete

revolutions does each wheel make to cover a distance of 1km 40m?​

Answer 1

Answer:

Okay

Your Answer

Step-by-step explanation:

The radius of the wheel being 60 cm, its circumference = (22/7)*2*60/100 = 3.771428571 m.

So to cover 132 m the wheel must rotate 132/3.771428571 = 35 times.

Answer 2

Step-by-step explanation:

1 m = 100 cm

70 cm = 0.7 m

and

1km 40 m in m

1040 m

now take circumference of circle

Radius=0.7 m

circumference= 2*22/7*7/10

4.4 m

revolutions are 4.4*1040

4576 is the answer
