we know that
surface area of cylinder=2*[area of the base]+perimeter of base*height

area of the base=pi*r²
r=3 m
area of the base=pi*3²----> 28.26 m²

perimeter of the base=2*pi*r
r=3 m

perimeter of the base=2*pi*3----> 18.84 m

surface area=226.08 m²
226.08=2*[28.26]+18.84*h----> 18.84*h=226.08-2*28.26
18.84*h=169.56-------> h=169.56/18.84-----> h=9 m

the answer is
9 m
