Formula for the surface area of a cylinder,
SA = 2/2 + 2nrh, for h
PLEASE HELPP

Step-by-step explanation:

Formula for the surface area of a cylinder;

   Surface area = 2r² + 2rh

  Problem:

 Make h the subject of the expression;

Solution:

  Given expression:

          S.A = 2r² + 2rh  

Add (- 2r² ) to both sides of the expression:

      S.A + ( -2r² ) =  ( -2r² ) +  2r²  + 2rh

          S.A -  2r²  = 2 rh

Divide both sides by  2r

         =

            h =
