Question 5 is to with Differentiation, might want to change the title.

Any, when you do  \displaystyle\frac{dy}{dx} of any constant, it's 0.

There's proof for it, but for now (if u want I can show u the proof), thats what u need to know.

Aren't you confusing differentiation and integration?

There is no integration, you're differentiating V.

As many have stated, you've misread the question, q5 is asking for the derivative of volume with respect to height, meaning differentiation, not integration. So the constant goes poof.
