V=PI x r^2 x (h/3)

3.14 x 3^2 x (4.5/3) = 42.39 in^3

Answer: [tex]42.39\text{ inches}^3[/tex]

Step-by-step explanation:

Given: The diameter of funnel = 6 inches

Then, Radius = [tex]r=\dfrac{6}{2}=3\text{ inches}[/tex]

Height = 4.5 inches

The formula to find the volume of a cone is given by :-

[tex]V=\dfrac{1}{3}\pi r^2 h[/tex]

i.e. [tex]V=\dfrac{1}{3}(3.14)(3)^2 (4.5)[/tex]

[tex]\Rightarrow\ V=42.39\text{ inches}^3[/tex]

Hence, the volume of the funnel =[tex]42.39\text{ inches}^3[/tex]
