Will give brainlist as soon as i can (as soon as i get 2 answers i can do it easily) for some reason i thought that this was 141.6

84.96 cm²

Step-by-step explanation:

Since the cylinders are similar then

ratio of heights = 3 : 5 , hence

ratio of areas = 3² : 5² = 9 : 25

let x be the surface area of the smaller cylinder, then by proportion

= ( cross- multiply )

25x = 2124 ( divide both sides by 25 )

x = 84.96

That is the surface area of the smaller cylinder is 84.96 cm²
