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

ch4aika [34]

Answer:

72,220 inches per minute

Step-by-step explanation:

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

1 revolution = $2\pi$ radians

$\frac{theta}{tome}=\frac{1000 \ revolution}{1 \ minuite} = \frac{1000* 2\pi }{1} =\frac{2000\pi}{1 \ minute}$

Speed $V= \frac{r*theta}{t}$

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

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

Speed $V= \frac{23}{2}*\frac{2000\pi}{1}$

Value of pi = 3.14

speed = 23000* 3.14= 72220 inches/ minute
