Respuesta:
[tex]154\pi cm^{2}[/tex] Ó [tex]483.56cm^{2}[/tex]
Explicación paso a paso:
[tex]Radio:r= 7cm[/tex]
[tex]Generatriz: g = 15cm[/tex]
[tex]Area-total: At = ?[/tex]
[tex]\pi =3.14[/tex]
Fórmula:
[tex]At = \pi rg+\pi r^{2}[/tex]
[tex]At = \pi (7cm) (15cm)+\pi (7cm)^{2} =105\pi cm^{2} + 49\pi cm^{2}[/tex]
[tex]At = 154\pi cm^{2}[/tex]
[tex]At = 154(3.14)cm^{2}[/tex]
[tex]At = 483.56cm^{2}[/tex]
