According to question
2 pi * r * h = 1760
2 * 22 * 14 * h/7 =1760
88 * h = 1760
h = 20

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

 \:  \:  \:  \:  \:  \:  \:  \:  \sf{radius \: of \: cylinder \:  = 14 \: cm}

  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \: \sf{height \: of \: cylinder \:  =  \:  ?}

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

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

  \:  \:  \:  \:  \:  \:  \: : ⟹ \sf{2 \times  \frac{22}{7}  \times 14 \times h = 1760}

  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \: : ⟹  \:  \: \sf{h =  \frac{1760 \times 7 }{2 \times 22 \times 14} }

  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:   \: \: : ⟹ \sf{ h = 20 \: cm}
