Answer:

l = [tex]\frac{S-\pi r^2}{\pi r}[/tex]

Step-by-step explanation:

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

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

[tex]\frac{S-\pi r^2}{\pi r}[/tex] = l

Answer:

[tex] l = \dfrac{S - \pi r^2}{\pi r} [/tex]

Step-by-step explanation:

[tex]S = \pi r^2+\pi rl[/tex]

[tex]\pi r^2+\pi rl = S[/tex]

[tex]\pi rl = S - \pi r^2[/tex]

[tex] l = \dfrac{S - \pi r^2}{\pi r} [/tex]
