The formula to calculate z-score is given by :_
For x= 9.96 mm, we have
For x= 10.01 mm, we have
The P-value =
Hence, the probability that a randomly selected gear has a diameter between 9.96 mm and 10.01 mm =0.2789

Answer:
26.22in²
Step-by-step explanation:
First get the radius using the formula of a circumference.
C = 2πr = 18.2
2(3.14)r = 18.2
6.28r = 18.2
Divide both sides by 6.28 to get r
r = 2.89
Now get the area of a circle using the formula:
A = πr²
A = 3.14(2.89)²
A = 3.14(8.35)
A = 26.22in²
