Question

a bicycle wheel is 1m 26 CM in diameter
1 the distance traveled in one rotation of the wheel ​

Answer 1

Step-by-step explanation:

Let the number of revolution of the wheel is n.

Since, radius=21

Then,

n × circumference of wheel = Distance travelled by bicycle

n×2π×21=1 kilometer 

n×π=1000 meter

n=π1000
