Question

A equals 2 pi r squared + 2 pi r h what is h equal to​

Answer 1

`h=(a)/(2\pi r)-r`

Explanation:

The equation in this problem is:

`a=2\pi r^2 + 2\pi r h`

We want to find an expression for h. Let's start by subtracting
`2\pi r^2` from both sides, we get:

`a-2\pi r^2 = 2\pi rh`

Now we divide both sides by
`2\pi r`, and we get:

`(a-2\pi r^2)/(2\pi r) = h`

And by simplifying,

`h=(a)/(2\pi r)-r`
