    Answer:

    Area = 87.9646  sq. units  from A = 28*π  sq. units.

    However I cannot see this in your answer list, since the numbers look all jumbled.  Choice A. looks close to it, since there is a 28…

    Step-by-step explanation:

    We have a cylinder with height h = 5

    radius = 2

    We want the surface area of this cylinder.

    A = (circumference)*h  + 2*(pi)*r^2

    A = ( 4*π)*5   + 2*π*(2^2)

    A = 20π + 8π  =  28 π   square units

    A = 87.9646 sq.. units
