Sagot :
Given:
Radius of cylinder = 3 cm
Height of cylinder = 25 cm
To find:
The plastic coating that would be needed to coat the surface of the chain link.
Solution:
We need to find the curved surface area of the cylinder to find the plastic coating that would be needed to coat the surface of the chain link.
Curved surface area of a cylinder is
[tex]C.S.A.=2\pi rh[/tex]
where, r is radius and h is height of the cylinder.
Putting π=3.14, r=3 and h=25 in the above formula, we get
[tex]C.S.A.=2(3.14)(3)(25)[/tex]
[tex]C.S.A.=471[/tex]
Therefore, the plastic coating that would be needed to coat the surface of the chain link is 471 cm².
