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 )
