Solution :
Given :
The mean height of an American adult = 5 feet 10 inches
Therefore converting feet into inches,
We know, 1 feet = 12 inches
So, 5 feet = 5 x 12 = 60 inches
The mean height in inches = 60+10
= 70 inches
The standard deviation = 3 inches
x = 5 feet 7 inches
= 5 x 12 + 7
= 67 inches
∴ z score = 



Therefore, the man's height is 1 standard deviation below mean
Any score above greater than 3 or less than -3 is considered to be an outliner.
Here its only -1 and it is less than -3.
Therefore, the height of the man 5'7'' is not considered abnormally short.
The area of the shaded face of the cylinder is 1,520 mm².
<h3>How to find the area of the shaded area?</h3>
We can see that the shaded area of the cylinder is circular in shape.
This means that we can find the area of the shaded area by finding the area of the circle.
The radius of the circle is given as 22 mm.
The formula for finding the area of a circle is given as:
<em>Area = πr²</em>
= 3.14 × 22 × 22
= 1,519.76
≈ 1520 mm²
Therefore, we have found the area of the shaded face of the cylinder to be 1,520 mm².
