Answer:

[tex]197.92in^{2}[/tex] or [tex]198in^{2}[/tex]

Step-by-step explanation:

Since Brittany does need to to cover the top and bottom, we can use the formula [tex]2\pi rh[/tex]

Let's first break down all the values that we already know.

h = 14 inches

diameter = 4.5

r = diameter / 2 = 2.25

Now that we broke down all our values, we then proceed to substitute all our values in the formula.

[tex]2\pi rh[/tex]

[tex]2\pi (2.25)(14)[/tex]

[tex]2\pi (2.25)(14)[/tex]

[tex]6.28(2.25)(14)[/tex]

[tex]14.14(14)[/tex]

= [tex]197.92in^{2}[/tex] or [tex]198in^{2}[/tex]
