Answer:
A. 251.2cm2
Step-by-step explanation:
Given radius of the cylinder 'r' = 2 cm
Given Height of the cylinder 'h' = 20 cm
Area of the curved surface = 2 π r h
The plastic coating would be needed to coat the surface of the chain link
A = 2 π r h
A = 2 × 3.14 ×2×20
A = 251.2 cm²
Conclusion:-
The plastic coating would be needed to coat the surface of the chain link
= 251.2 cm²
Answer:

Answer:
Hence, the two numbers chosen or plotted by them are:
-75 and 75
Step-by-step explanation:
It is given that Bernita and Derek each plot a number on a number line with the properties:
- The two numbers they have plotted are unique or different.
- Also there absolute value is same.
- The sum of the absolute values of the numbers is 150.
<em>We know that</em><em> Absolute value</em><em> of a positive number is a number itself and absolute value of a negative number is it's inverse.</em>
Hence, the two numbers that satisfy the above three properties are:
-75 and 75.
Since,
|-75|=75
and |75|=75.
Hence, |-75|=|75|
Also |-75|+|75|=75+75=150
$200 without the discount and he payed $136.
