    Correct answer: 4, 9, 25, 100

    Step-by-step explanation:

    Surface area of cylinder A = 2r²π + 2rπ h = 2rπ (r+h)

    r₁ = 2r and h₁ = 2h = > A₁ = 2 (2r) π (2r+2h) = 2 2rπ 2 (r+h) = 4 2rπ (r+h)

    A₁ = 4 A

    r₁ = 3r and h₁ = 3h = > A₁ = 2 (3r) π (3r+3h) = 3 2rπ 3 (r+h) = 9 2rπ (r+h)

    A₁ = 9 A and so on ...

    God is with you!
