I've been learning about integrals and I am not understanding these questions.

Hi, I have attached a file (picture).

I've been learning about integrals and I am not understanding these questions.

Can you help me to understand calculus problems and walk me through the questions please?

Can you walk me through #1?

I am literally asking one question with sub questions -- not too many components...

Thanks.
