Question

What is the best result for h?

Answer 1

I think the first option is the correct one

Hope this helps:)

Answer 2

Answer: First option.

Explanation:

To solve for "h" from the given the equation
`S=2\pi rh+2\pi r^2`, you need to:

Apply the Subtraction property of equality and subtract
`2\pi r^2` to both sides of the equation.

Then you need to apply the Division property of equality and divide both sides of the equation by
`2\pi r`.

Then:

`S-2\pi r^2=2\pi rh+2\pi r^2-2\pi r^2\\\\S-2\pi r^2=2\pi rh\\\\(S)/(2\pi r)-(2\pi r^2)/(2\pi r)=(2\pi rh)/(2\pi r)\\\\(S)/(2\pi r)-r=h`
