Answer:
c) 345.4 cm²
The plastic coating would be needed to coat the surface of the chain link
= 345.4 cm²
Step-by-step explanation:
<em>Given radius of the cylinder 'r' = 2.5 cm</em>
<em>Given Height of the cylinder 'h' = 22 cm</em>
<em>Area of the curved surface = 2 π r h </em>
<em>The plastic coating would be needed to coat the surface of the chain link</em>
<em> A = 2 π r h </em>
<em> A = 2 × 3.14 ×2.5×22 </em>
<em> A = 345.4 cm²</em>
<u><em>Conclusion</em></u><em>:-</em>
<em>The plastic coating would be needed to coat the surface of the chain link</em>
<em> = 345.4 cm²</em>
