Given:
Radius = 1.75 m
Distance traveled = 11 km
To Find:
The number of revolutions
Solution
Find the circumference:
Circumference = 2πr
Circumference = 2π(1.75)
Circumference = 3.5π
Circumference = 11 m
Find the number of revolutions:
Total distance traveled = 11 km
Total distance traveled = 11 000 m
One revolution = circumference
One revolution = 11 m
Number of revolution = 11 000 ÷ 11
Number of revolution = 1 000
Answer: 1000 revolution
