The formula of a volume of a cone:
[tex]V=\dfrac{1}{3}Bh=\dfrac{1}{3}\pi r^2h[/tex]
We have:
[tex]r=12cm,\ h=8cm[/tex]
Substitute:
[tex]V=\dfrac{1}{3}\pi\cdot12^2\cdot8=\dfrac{1}{3}\pi\cdot144\cdot8=\pi\cdot48\cdot8=384\pi\ cm^2\approx384\cdot3.14=1205.76\ cm^3\approx1206\ cm^3[/tex]
Answer: 1206 cm³
