Answer 1

$\Huge{\mathfrak{\red{\underline{\underline{AnSweR;}}}}}$

$\large{\textbf{\textsf{Given;}}}$

$\large{\textbf{\textsf{Radius\:=\:14cm}}}$

$\large{\textbf{\textsf{Total\:Surface\:Area\:of\:Cylinder\:=\:2*22/7*r(h+r)}}}$

$\textbf{\textsf{\:\:\:Putting \:The\:Value\:Of\:TSA}}$

$\large{\textbf{\textsf{1936cm^2\:=\:2\times{22/7}\times{r}\times(h+r)}}}$

$\large{\textbf{\textsf{1936cm^2\:=\:2*22/7*14*(h+14)}}}$

$\large{\textbf{\textsf{1936cm^2\:=\:88(h+14)}}}$

$\large{\textbf{\textsf{1936cm^2\:=\:88h+88*14}}}$

$\large{\textbf{\textsf{1936-1232\:=\:88h}}}$

$\large{\textbf{\textsf{704 cm^2\:=\:88h}}}$

$\large{\textbf{\textsf{h\:=\:704cm^2/88cm}}}$

$\huge{\boxed{\textbf{h\:=\:8cm}}}$
