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 = radians
Speed
r is the radius , theta is the angle and t is the time
We know diameter = 23 , then radius = 23/2
Speed
Value of pi = 3.14
speed = 23000* 3.14= 72220 inches/ minute
The mistake is there is no parenthesis around 4x+12
