Answer:
[tex]\pi =\frac{S}{2rh}[/tex]
Step-by-step explanation:
[tex]S= 2\pi rh[/tex]
We need to solve for π. for that we need to get π alone
To isolate π, we eliminate 2rh from the right side
WE divide both sides by 2rh
[tex]S= 2\pi rh[/tex]
[tex]\frac{S}{2rh} =\frac{2\pi rh}{2rh}[/tex]
[tex]\pi =\frac{S}{2rh}[/tex]
