Answer:792 cm^2Step-by-step explanation:Lengthoftherectangularsheet=Basecircumferenceofthecylinder=44cmBreadthoftherectangularsheet=Heightofthecylinder=18cmSo,CurvedSurfaceAreaofthecylinder[tex] = 2\pi rh[/tex][tex] = 44 \times 18 \: {cm}^{2} [/tex][tex] = 792 \: {cm}^{2} [/tex]Hence,CurvedSurfaceAreaofthecylinderis792cm^2.Step-by-step explanation:Let the height be 18cm

therefore, circumference of base 44cm

so, radius is 44*7/2*22

= 7

CSA of cylinder= 2πrh

= 2*22/7*7*18

= 792
