Answer:
D) SA - πr²
. πr
Step-by-step explanation:
Rearrange the equation to isolate s (separate it from everything else).
SA = πrs + πr² s is in πrs, so start by moving the other term: πr²
SA - πr² = πrs Subtract πr² from both sides. It cancels out on the right
(SA - πr²)/πr = s Divide both sides by πr
s = SA - πr²
. πr
