Please help and thank you

Answer 1

B. l = (S - πr^2) / πr

Explanation:

S = πrl + πr^2 solve for l

πrl = S - πr^2

l = (S - πr^2) / πr

Answer is B. l = (S - πr^2) / πr

Answer 2

Solve for L (get L by itself)

S = πrl + πr² First subtract πr²

S - πr² = πrl Then divide πr to get L by itself

(S-πr²) ÷ (πr) = l Your answer is B
