SAcylinder=sides+top and bottom

top=circumference times height

top and bottom=2 itmes circle

d=18

d/2=18/2=9=r

top and bottom=2pir^2=2pi9^2=2pi81=162pi

sides

c=2pir=18pi

height=12

sidearea=18*12*pi=216pi

add

162pi+216pi=378pi ft^2

Surface area of a cylinder = 2πr^2 + 2πrh = 2π x (18/2) ^2 + 2π x (18/2) x 12 = 162π + 216π = 378π ft^2
