Question

PLEASE HELP UREGET GEOMETERY

Answer 1

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

`V= \frac 1 3 \pi r^2 h = \frac 1 3(4^2)(32)`

Third choice

~~~~~~~~~~~~~~~~~~~~~~~~~~

`182.8 \textrm{ ml} * 0.135 \textrm{ g/ml} = 24.678 \textrm{ g}`

Answer: 24.68

Vase

`V_v=\pi r_v^2 h`

Marble

`V_m= \frac 4 3 \pi r_m^3`

We have
`r_v=6/2, h=12, r_m=3/2`

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

Second choice

Answer 2

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