Given:
it is given that thw height of a cone is 9 ft and base diameter is 12 ft.
Find:
we have to find the Volume of the cone.
Explanation:
we know the volume of the cone with height h and radius r is
[tex]V=\frac{1}{3}\pi r^2h[/tex]
here height (h) = 9 ft
diameter d = 12 ft
Therefore, radius r = 12/2 = 6 ft
The Volume of the cone is
[tex]V=\frac{1}{3}\pi(6)^2\times9=\frac{1}{3}\times(3.14)\times36\times9=339.12\text{ }ft^3[/tex]
Therefore, the volume of the given cone is 339.12 ft^3
