Question

A car's wheels spins at 1000 revolutions per minute. The diameter of the wheels is 23 inches. You want to know how fast the car is traveling, so what is the speed?Thank you

Answer 1

72,220 inches per minute

Explanation:

Answer 2

72,220 inches per minute

Explanation:

A car's wheels spins at 1000 revolutions per minute. The diameter of the wheels is 23 inches.

1 revolution =
`2\pi` radians

`(theta)/(tome)=(1000 \ revolution)/(1 \ minuite) = (1000* 2\pi )/(1) =(2000\pi)/(1 \ minute)`

Speed
`V= (r*theta)/(t)`

r is the radius , theta is the angle and t is the time

We know diameter = 23 , then radius = 23/2

Speed
`V= (23)/(2)*(2000\pi)/(1)`

Value of pi = 3.14

speed = 23000* 3.14= 72220 inches/ minute
