Answer:
Angle of rotation of bike's tire is = 6.29°
Step-by-step explanation:
Given: radius of bike's tires 14 inches
bike rolls forward 18 inches
To find: the angle of rotation of the bike's tire
we know that,
Angle of rotation = [tex]\frac{distance covered by bike}{radius of bike's tire}[/tex]
distance covered by bike is equal to the circumfernce of circle
we know that, circumference of circle = 2πr
=2×[tex]\frac{22}{7}[/tex]×14
circumference of circle =88.
Angle of rotation =[tex]\frac{88}{14}[/tex]
= 6.29°
