The radius of the cars tier is 0.04m
A circumference is a line that goes around or encircles a circle.
The radius of a circle is the distance between the circle's center and any point on its circumference.
Given that
The number of revolutions = 100 m/s
Speed of car = 30 m/s.
Formula used:
Circumference of wheel = 2 [tex]\pi[/tex]r
Distance in one revolution = 30/100
Distance in one revolution = 0.3 m
This gives that the circumference of the wheel is 0.3 is equal to 2πr, where r is the radius of the tire
0.3 = 2 x 22/ 7 x r , where [tex]\pi[/tex] = 22/7
⇒ r = 2.1/44,
⇒ r = 0.04 m
Therefore the radius of the car's tier is 0.04 m.
