Answer is B. No matter what the x or y will be the result will be 0. Anything multiplied by 0 is equal to 0.
Since there are 2 sides to the shelf, there is 0.05*2=0.05+0.05=0.1 meters of space between the shelf and wall in total. Next, since each piece of wood is 0.3 meters wide and we have 3 of them, the total width of the wood is 0.3+0.3+<something>
Note that <width of wood>+<space between shelf and well> =width of closet

Here we get the statement:
"sec^-1(0.5) is undefined"
And we want to see if this is true or false, so let's use the properties that we know to find that this is false.
Remember that the sec function is defined as:

Then we will have:

Then is really trivial to see that:

Then we can conclude that the function is not undefined at 0.5, so the statement is false.
Below you can see the graph of the given function, and you will see that it is never undefined.

We know, Volume of a Cone = πr² h/3
v = 3.14 * (11)² * 4.5/3
v = 3.14 * 121 * 1.5
v = 569.91 in³
In short, Your Answer would be Option C
Hope this helps!
