The amount of metal used to make the can = surface area of cylindrical can, which is: D. 42π in².
<h3>What is the Surface Area of a Cylinder?</h3>
A can is a cylinder.
Surface area of a cylinder = 2πrh + 2πr²
Thus:
Amount of metal used to make the can = surface area of the can
r = 6/2 = 3 in.
h = 4 in.
Therefore:
Surface area = 2×π×3×4 + 2×π×3²
Surface area = 24π + 18π
Surface area = 42π in².

Answer:
x = 2.55 (rounded)
x = 2. 5454545455 (exact)
Step-by-step explanation:
We can change this sentence, into a mathematical expression and solve:
5.5 · x = 14
x = 14 / 5.5
x = 2.5454545
x = 2.55 (rounded)
