How much food can this container hold express your answer in terms of

volume of a cone = 1/3*(πr²h)

Step-by-step explanation:

The Volume of a cone can be expressed using the formula

volume of a cone = 1/3*(πr²h)

Now if r=3 in and h= 9 in

= 1/3( π (3)²9)

= 27Π in 3

its a straight line parallel to the time axis

graphically?   well, you graph them both, the solutions is where they both intersect each other, since there are two solutions, meaning they will meet twice, or namely the linear will run into the quadratic curve twice, and where they meet, those x,y coordinates are the solutions to the system.
