How do I solve this literal equation? <br> 15 points

kati45 [8]

Answer:

$\pi = \frac{A}{2r^2 + 2rh}$

Step-by-step 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:

$A=\pi (2r^2 + 2rh)\\\pi = \frac{A}{2r^2 + 2rh}$

This is the xpression for $\pi$
