Surface Area formula of a cylinder: S.A = 2 × Area of base + Perimeter of base × Height of prism = 2[tex] \pi [/tex]r² + 2[tex] \pi [/tex]rh = 2[tex] \pi [/tex](5)² + 2[tex] \pi [/tex](5)(18) = 50[tex] \pi [/tex] + 180[tex] \pi [/tex] = 230[tex] \pi [/tex] in² ( in terms of [tex] \pi [/tex] ) = 722.566 in² = 722.7 in² ( to the nearest tenth )
