Given that the radius of the wheel is 10 inches and its rate of turn is 8 revolutions per second.
The speed of the car= 8 times the circumference of the wheel.
Recall the formula for the circumference of the circle is
[tex]C=2\pi r[/tex]Substitute r=10, we get
[tex]C=2\times3.14\times10=62.8\text{ inches.}[/tex]the circumference of the wheel is 62.8 inches.
The speed of the car= 8 times the circumference of the wheel.
The speed of the car= 8 times 62
