In one revolution, the bicycle covers a distance equal to the circumference of the wheel.
So, in one revolution, the bicycle covers
[tex]C=2 \pi r=2* \frac{22}{7}*0.42(m)= 44*0.06(m)=2.64 (m)[/tex]
In a distance of 66 m the bicycle makes [tex] \frac{66}{2.64}= 25[/tex] revolutions
Answer: 25 revolutions
