Answer:
345.4 cm²
Step-by-step explanation:
We solve this above question using the formula of Lateral surface area of a cylinder because we are asked to find the amount of paint that would only cover the body of the cylinder not the total cylinder
Lateral surface area of a cylinder = 2Ï€rh
= π = 3.14
r= 2.5cm
h = 22 cm
Hence:
2 × 3.14 × 2.5 × 22
= 345.4cm²
Therefore, the amount of plastic coating that would be needed to coat the surface of the chain is 345.4 cm²
