n200080 [17]
Can you attach the graph? 

But what you have to do is do find -2 on your graph and see the point there. Since f(-2) needs to have -2 in the x of the point, the (-3,0) and (1,0) dont matter. So check your graph for the points (-2, 2) and (-2, 1). Whatever point on your graph matches, then thats the answer

Zepler [3.9K]

The volume of the air space surrounding the cone inside the cylinder is 1055.04 cm³

<h3 />

<h3>How to find volume?</h3>

The volume of the air space surrounding the cone inside the cylinder is as follows:

volume of the air space = volume of cylinder - volume of a cone

volume of cylinder = πr²h

volume of cylinder = π16 × 5²

volume of cylinder = 400π

volume of the cone = 1 / 3 πr²h

volume of the cone = 1 / 3 × π × 12 × 4²

volume of the cone = 64π

Therefore,

volume of the air space = 400π - 64π

volume of the air space = 336π

volume of the air space = 1055.04 cm³
