Please help, neither me nor my parents understand this.
In English, we would say:
"Please help. Neither my parents nor I understand this"
You wouldn't say "me understand"
It is still polite and correct grammar to list yourself last.
Hints.
Direct variation y=kx where k is some number/constant
Indirect or inverse variation y=k/x
Proportion means in the form of a fraction
Your first problem would be v=k*r^3
