Step-by-step explanation:
you will use simple math operations
first you will use common factor of 2pir
[tex]s = 2\pi \times rh + 2\pi \times r ^{2} [/tex]
[tex]s = 2\pi r(h + r)[/tex]
and divided s by it .t
Then subtract r from both sides and you will get h from one side
[tex] \frac{s}{2\pi r} = h + r[/tex]
[tex] \frac{s}{2\pi r} - r = h[/tex]
