Answer:
r = 10.5 m
Step-by-step explanation:
Given that,
A bicycle wheel turns 15 times in covering a distance of 66 m.
We need to find the radius of the wheel.
The distance that a wheel travels in one rotation is simply the circumference of the circle.
[tex]2\pi r=66[/tex]
Where
r is the radius of the wheel
Put all the values,
[tex]r=\dfrac{66}{2\pi}\\\\r=\dfrac{66\times 7}{2\times 22}\\\\r=10.5\ m[/tex]
So, the radius of the wheel is equal to 10.5 m.
