Respuesta :

1/3(3.14)(4cm)^2(32cm) this should be correct :)

Cone diameter d=8, h=4d=32. Radius r=d/2=4.

[tex]V= \frac 1 3 \pi r^2 h = \frac 1 3(4^2)(32) [/tex]

[tex]182.8 \textrm{ ml} \times 0.135 \textrm{ g/ml} = 24.678 \textrm{ g}[/tex]

Answer: 24.68

Vase

[tex]V_v=\pi r_v^2 h[/tex]

Marble

[tex]V_m= \frac 4 3 \pi r_m^3[/tex]

We have [tex]r_v=6/2, h=12, r_m=3/2[/tex]

[tex]V = V_v - 7 V_m = \pi 3^2 (12) - 7(\frac 4 3 \pi (3/2)^3)[/tex]

Second choice
