ayuda xfavor necesito urgente​

Answer 1

Respuesta:

9. A lateral = 135.09 cm2

A total= 213.63 cm2

V= 183.26 cm3

10. A lateral = 544 cm2

A total= 798.47 cm2

V= 1441.99 cm3

Explicación paso a paso:

Area lateral del cono = π*radio*generatriz

Area de la base = π*radio^2

Volumen=π*radio^2*altura

9. Area lateral:

$g=\sqrt{r^{2}+h^{2} }=\sqrt{5^{2}+7^{2} }=8.6\\A=\pi (5)(8.6)=135.09cm^{2}$

Area de la base:

$A=\pi (5^{2} )=78.54cm^{2}$

Area total: 135.09+78.54=213.63 cm2

Volumen:

$V=\frac{1}{3} \pi (5^{2} )(7)=183.26cm^{3}$

10. Area lateral:

$g=\sqrt{r^{2}+h^{2} }=\sqrt{9^{2}+17^{2} }=19.24\\A=\pi (9)(19.24)=544cm^{2}$

Area de la base:

$A=\pi (9^{2} )=254.47cm^{2}$

Area total: 544+254.47=798.47 cm2

Volumen:

$V=\frac{1}{3} \pi (9^{2} )(17)=1441.99cm^{3}$
