Can someone please help me it's worth five points

Answer 1

The formula of a volume of a cone:

`V=(1)/(3)Bh=(1)/(3)\pi r^2h`

We have:

`r=12cm,\ h=8cm`

Substitute:

`V=(1)/(3)\pi\cdot12^2\cdot8=(1)/(3)\pi\cdot144\cdot8=\pi\cdot48\cdot8=384\pi\ cm^2\approx384\cdot3.14=1205.76\ cm^3\approx1206\ cm^3`

Answer: 1206 cm³
