Any shape can contain material into it that is equal to its volume.
So, this cone can hold as much food as its volume.
Volume of a cone=[tex] \pi r^{2} \frac{h}{3} [/tex]
here, r(Radius)= diameter/2= [tex] \frac{3}{2}[/tex] in.
and h(Height)=7in.
and [tex] \pi =3.14[/tex]
So;
[tex]Volume=3.14*( \frac{3}2} )^{2} * \frac{7}{3} =16.485 in.^3[/tex]
Answer is 16.49[tex]in^3[/tex]
Hope this helps!
