Answer:

176cm square

Step-by-step explanation:

volume = 112π cm³.

radius = 4cm

we know that,

volume = π*r*r*h

112π = π*4*4*h

112/16 = h

therfore h = 7cm.

now we know that,

curved surface area of the cylinder = 2*π*r*h

                                                             = 2*22/7*4*7

                                                             = 2*22*4 = 176cm²(Ans)
