Question

V = π r2h for h

Answer 1

Try to get h alone.
The opposite of multiplication is division.
If you divide all the terms on the right side (except h) by both sides it will
i) cancel all the items on the right (except h) and
ii) give you the answer.

Can you do that @samanthasal?

Answer 2

h = V / (Pi * r square)

keep h on one side .. and push all the terms on another side..
