Answer:

[tex]18\pi[/tex] ft cubed

Step-by-step explanation:

The volume of a cone is: [tex]V=\frac{1}{3} \pi r^2h[/tex] , where [tex]\pi r^2[/tex] is the base and h is the height.

In this case, we see that the base is: [tex]\pi r^2=9\pi[/tex]. Solving for r, we see that the radius is [tex]\sqrt{9} =3[/tex].

The height is twice the radius, so h = 2 * 3 = 6. Now, we have all the necessary values that we can plug into the equation to get the volume:

[tex]V=\frac{1}{3} *9\pi *6=18\pi[/tex]

Thus, the answer is [tex]18\pi[/tex] ft cubed.

Hope this helps!

Answer:

18π ft³

Step-by-step explanation:

Base area = pi × r² = 9pi

r² = 9

r = 3

h = 3 × 2 = 6

Volume = ⅓ × pi × r² × h

⅓ × 9pi × 6

18pi ft³
