    Answer:

    Surface Area = 150.8 square inch

    Step-by-step explanation:

    Surface \ Area = 2 \pi r h + 2 \pi r^2  \ \ \ \ \ \ \  \ \ \ \ \ \ [ \ r = 4 , \ h = 2 \ ] \\\\

                        = 2 \pi \times 4 \times 2 + 2 \pi 4^2\\\\=16 \pi + 32 \pi \\\\= 48 \pi \\\\= 150.796 \\\\=150.8 \ square \ inch
