Answer: 251.2cm^2
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

We need a picture added- You can't just have "Help" xD add a pic in the next one and I'll see what I can do
Hey there!
"15 more than" will mean that 15 will be added to another term. The other term is "half a number", meaning 0.5x, where x is the number. This equation is equal to 9. The final equation is 0.5x + 15 = 9.
To solve this, cancel out the terms until you find what x is equal to:
0.5x + 15 = 9 (subtract 15 from both sides)
0.5x = –6 (divide both sides by 0.5)
x = –12 (final answer)
Hope this helped you out! :-)
