Answer:

Renee

Explanation:

We have the formula for total surface area of a cylinder as

A = 2 \pi r^2 + 2 \pi rh

First switch sides so the h term is on the left side:

2 \pi r^2 + 2 \pi rh = A

Subtract
2\pi r^2 from both sidess:

2 \pi rh = A - 2 \pi r^2

Divide both sides by
2 \pi rh:

h = (A-2\pi r^2)/(2\pi r)

This corresponds to Renee's answer so Renee is correct
