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
Answer:
40 degrees
Step-by-step explanation:
We know the entire angle of ABD is 70 and CBD and ABC are in it.
Since we know one of them (CBD) is 30, we can subtract 30 from 70 to find ABC. This is because the angle of ABC and CBD equal ABD.
30 + x = 70
-30 from both sides
x = 40
