Explicación paso a paso:
Solución:
Diámetro: D = 12 cm
Radio: r = 6cm
Altura: h = 15cm
Area Total: At = ?
Fórmula(s):
Area Lateral: [tex]AL = 2\pi rh[/tex]
Area de la base: [tex]A_{B} = 2\pi r^{2}[/tex]
Area total: At = AL + [tex]A_{B}[/tex]
[tex]At = 2\pi rh + 2\pi r^{2}[/tex]
[tex]At = 2\pi r(h+r )[/tex]
Reemplazando:
[tex]At = 2\pi * 6cm ( 15cm+6cm) = 2\pi *6 *(15+6)cm^{2}[/tex]
RESPUESTA:
[tex]2\pi * 6 * (15+6) cm^{2} ;[/tex] La correcta es la Opción d )
