208.81 square centimeters of aluminium are needed
<em><u>Solution:</u></em>
Given that,
Radius = 3.5 cm
Height = 6 cm
We have to find the square centimeters of aluminum needed
So we have to find the surface area of cylinder
<em><u>The surface area of cylinder is given by formula:</u></em>

Where "r" is the radius and "h" is the height of cylinder
<em><u>Substituting the values we get,</u></em>

Thus 208.81 square centimeters of aluminium are needed
516+497+501+528+476= 2518
2518/5= 503.6
round up to 504
I hope i’m correct. Hope this helps!
Depends how you were taught to solve it but if it were me I’d choose B) minimum value at -6
