Answer:

l =
(S-\pi r^2)/(\pi r)

Explanation:

S = πr² + πrl ( subtract πr² from both sides )

S - πr² = πrl ( isolate l by dividing both sides by πr )


(S-\pi r^2)/(\pi r) = l

Answer:


l = (S - \pi r^2)/(\pi r)

Explanation:


S = \pi r^2+\pi rl


\pi r^2+\pi rl = S


\pi rl = S - \pi r^2


l = (S - \pi r^2)/(\pi r)
