Question

a bicycle wheel makes 5000 revolution in moving 11 km find the circumference and the diameter of the wheel

Answer 1

no. of revolution = 5000
distance=11km

no. of revolution =distance travelled by wheel/.
circumference of wheel

5000=11/circumference
11/5000=circumference
circumference=2.2m

Answer 2

Heya Mate...................................

Here is your answer...................................

____________________________________________________________________________________

The bicycle makes 5000 revolution = 11000m

So, the bicycle make 1 revolution = 11000/5000m

Circumference = 11/5m

2πr = 11/5

πd = 11/5

22/7 * d = 11/5

d = 11*7/5*22

d = 77/110

d = 7/10

d = 0.7m

d = 0.7*100cm

d = 70cm
