Answer:
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 )
Answer:
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
