Question

Someone please please help ASAP

Answer 1

Answer:

$l = \frac{A}{\pi r}-2$

Step-by-step explanation:

A = 2πr + πrl

A - 2πr = 2πr + πrl - 2πr  (subtracting both sides by 2πr)

A - 2πr = πrl

$\frac{A - 2\pi r}{\pi r} = \frac{\pi rl}{\pi r}$                      (dividing both sides with πr)

$\frac{A}{\pi r} - \frac{2\pi r}{\pi r} = l$                      (splitting LHS)

$\frac{A}{\pi r}-2=l$

$l = \frac{A}{\pi r}-2$
