Answer:
Step-by-step explanation:
This is a literal equation, and for some reason, students literally freak out about solving them. We will isolate h the same way we would if we were solving an equation for x. In order to get the term with the h in it all by itself, we have to move everything else away from that term. The 2πr² is added on the left, so we will move it by subtracting it from both sides, giving us
Then we need to get the h alone. Everything on the right side of the equals sign is multiplied together, so the "undoing" of multiplication is division, so that's what we'll do. Divide everything away from the h:
which is choice C.
