357.96 mm 2
339.12 mm 2
370.52 mm 2

Answer 1

357.96

Answer 2

thanks

Answer 3

welcome :)

Answer 4

\[total\ surface\ area\ of\ cylinder\ = curved\ surface\ area\ + lateral\ surface\ area \\ suppose\ radius\ of \ cylinder\ = r\\height\ of\ cylinder \ =h\\ total\ surface\ area=2\pi rh+2\pi r^2\\=2\pi r(h+r)\\=2\times3.14\times3(16+3)\ mm^2\\=2\times3.14\times3\times19\ mm^2\\=357.96\ mm^2\\ \therefore\ \approx.\ surface\ area =357.96\ mm^2\ |Ans\]
