Step-by-step explanation:
[tex]Greetings![/tex]
[tex]I'm~Isabelle~Williams~and~will~be~answering~your~question![/tex]
[tex]To~find~the~surface~of~a~cylinder,~we~use~the~formula~that~is:[/tex]
[tex]\boxed{~A=2\pi r ~h+2\pi r^2~}[/tex]
[tex]In~our~case~we~have:[/tex]
[tex]=2\times \pi \times 7\times 12+2\times \pi \times 7^2[/tex]
[tex]=835.66cm^2[/tex]
[tex]Thus,~the~surface~area~of~this~cylinder~is~835.66cm^2.[/tex]
[tex]Hope~this~helps~and~have~an~amazing~day~ahead![/tex]
