Answer 1

`\pi = (A)/(2r^2 + 2rh)`

Explanation:

First, we need to isolate
`\pi` by taking it common from both terms on the right:

`A=2\pi r^2 + 2\pi rh\\A=\pi (2r^2 + 2rh)`

Now, since we want
`\pi` in terms of the other variables, we can divide the left hand side (A) by whatever is multiplied with
`\pi` on the right hand side. Then we will have an expression for
`\pi`. Shown below:

`A=\pi (2r^2 + 2rh)\\\pi = (A)/(2r^2 + 2rh)`

This is the xpression for
`\pi`
