The diameter of the cone is d = 6 ft.
The height of cone is h = 8 ft.
Determine the radius of cone.
[tex]\begin{gathered} r=\frac{d}{2} \\ =\frac{6}{2} \\ =3 \end{gathered}[/tex]
Determine the volume of cone.
[tex]\begin{gathered} V=\frac{\pi(3)^28}{3} \\ =\frac{\pi\cdot9\cdot8}{3} \\ =3\cdot3\cdot8 \\ =72 \end{gathered}[/tex]
So volume of cone is 72 feet cube.
Answer: 72
