Answer:
No. of complete revolutions = 20
Step-by-step explanation:
Given:
Distance covered by the bicycle = 40 m
Radius of the bicycle wheel = 32.5 cm = 0.325 m
Conversion:
⇒
We have to find the number of revolution the front wheel make.
Let the no. of revolution be "N" .
As we know that:
Circumference times no. of revolution = Distance covered by circular objects.
Circumference = 2πr
So,
⇒ ![Distance\ covered=N\times 2\pi (r)](https://tex.z-dn.net/?f=Distance%5C%20covered%3DN%5Ctimes%202%5Cpi%20%28r%29)
⇒ ![\frac{Distance\ covered}{2\pi(r) } =N](https://tex.z-dn.net/?f=%5Cfrac%7BDistance%5C%20covered%7D%7B2%5Cpi%28r%29%20%7D%20%3DN)
⇒ Plugging the values.
⇒ ![\frac{40}{2\pi(0.325) } =N](https://tex.z-dn.net/?f=%5Cfrac%7B40%7D%7B2%5Cpi%280.325%29%20%7D%20%3DN)
⇒ ![\frac{40}{2.04} =N](https://tex.z-dn.net/?f=%5Cfrac%7B40%7D%7B2.04%7D%20%3DN)
⇒ ![19.6=N](https://tex.z-dn.net/?f=19.6%3DN)
Approximated to 20.
Number of complete revolutions,the front wheel make = 20
