Question

A bicycle wheel has a diameter of 70 centimeters. If the wheel completes 10,000 revolution while rolling in a straight line without slipping, how many kilometers does the wheel travel? Round your answer to the nearest kilometer. (100 centimeters=1meter, 1000 meters= 1 kilometer

Answer 1

circumference = pi*d
one rotation = one circumference distance travelled
since you need this in kilometer,
first convert 70 cm to km
then calculate the circumference and multiply by 10000

Answer 2

Answer 3

1000 cm = 1m
1000m = 1km

Answer 4

1000000 cm = 1 km
