The wheels of a bicycle have a diameter of 70cm. How many meters will the bicycle travel if each wheel makes 50 revolutions

see explanation

Step-by-step explanation:

1 revolution is equivalent to the circumference of the wheel

1 revolution = πd (d is the diameter)

= 70π cm

50 revolutions = 70π * 50 = 3500π cm = 35π m ≈ 110m (nearest metre)

109.956 m

Step-by-step explanation:

The first step is to find the circumference of the wheel.

C = πd

where d = diameter of the wheel

C = πd

= π * 70

= 219.9 cm.

In every revolution the bicycle move 219.9 cm.

In 50 revolution the bicycle will make = 219.9 * 50

= 10,995.6 cm

In meter = 10,995.6 : 100

= 109.956 m
