Answer:

427.04 in²

Step-by-step explanation:

Surface area = 2[tex]\pi[/tex]rh + 2[tex]\pi[/tex]r²

[tex]A = 2\pi (8)(0.5) + 2\pi 8^2[/tex]

[tex]A = 2\pi 4 + 2\pi 64[/tex]

[tex]A = 25.12 + 401.92[/tex]

[tex]A = 427.04[/tex]

So, the surface area of the cylinder is 427.04 in² which is answer choice D.
