  \:  \:  \:  \:  \:  \:  \: \sf{height \: of \: cylinder} = 20cm

  \:  \:  \:  \:  \: \sf{curved \: surface \: area \:  = 1760 \:  {cm}^{2} }

 \:  \:  \:  \:  \:  \:  \:  \:  \red{ \boxed{ \sf{csa \: of \: cylinder = 2\pi rh}}}

 \:  \:  : ⟹     \:  \:\:  \:  \:  \:  \:  \:  \:  \:  \sf{2\pi  rh = 1760}

 \:  \:  \:  \:   \:  \: :   ⟹   \sf {2 \times \ \frac{22}{7} \times r \times 20 = 1760}

 \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  : ⟹  \sf{r =   \frac{1760 \times 7}{2 \times 22 \times \times 20 } }

 \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  :   ⟹ \sf{r = 14 \: cm}

 \:  \:  \:  \:  \:  \:  \:  \pink{ \boxed{ \sf{volume \: of \: cylinder = \pi r {}^{2} h}}}

 \:  \:  \:    \:  \:  \: : ⟹ \:  \:  \:  \:  \sf{ \frac{22}{7}  \times 14 \times 14 \times 20}

  \:  \:  \:  \:  \:  \:  \:  \:  \:  \: :  ⟹ \:  \: 22 \times 2 \times 14 \times 20

   \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \: : ⟹ \:  \:  \:  \sf {12320  \:  \: {cm}^{3} }
