Question

S=πrl+πr2 solve for l.

Answer 1

Answer:

$l = \frac{s - π {r}^{2} }{πr}$

Step-by-step explanation:

s = πrl + πr²

First move πr² to the left side of the equation

We have

πrl = s - πr²

Divide both sides by πr to make l stand alone

That's

$\frac{\pi \:rl}{\pi \: r} = \frac{s - \pi \: {r}^{2} }{\pi \: r}$

We have the final answer as

$l = \frac{s - π {r}^{2} }{πr}$

Hope this helps you
