Step-by-step explanation:
diameter of cylinder=18.5
lenght =6.1
lenght=height=6.1
radius=diameter/2
= 18.5/2
=9.5
curved surface area of cylinder=2πrh
=2×22/7×9.5×6.1
=364.2571428m²
but my answer is different

diameter = 18.5
Then, radius = diameter/2
= 18.5/2
=9.25
length (height) = 6.1 m
Curved surface area= 2 πrh
=(2×22/7×9.25 ×6.1) m^2
=(354.671429) m^2
=3546714.29 cm^2
