Question

the diameter of cart wheel is 2.1 mts find distance travelled when it completes 100 revolutions

Answer 1

Circumference of wheel=πd

Circumference of wheel =22*2.1/7

Circumference of wheel =6.6 Mrs

It coveres 6.6mtrs in one round

Then in 100 rounds it will take 6.6*100=660mtrs

Answer 2

Hey,,,,
distance=no.of revolutions *circumference
Now,
circumference =2πr
=2*22/7*2.1/2
=6.6m
Therefore,
distance=6.6*100
=660m.
Hope this helps you!! :)
