First simplify the right-hand side:
A = πRh + 2πRh = 3πRh.
Now solve for R (assuming h ≠ 0):
R = A / (3πh).
If you meant A = πR^2 + 2πRh (the cylinder surface area), the solution for R is from the quadratic
πR^2 + 2πhR − A = 0, giving
R = −h + sqrt(h^2 + A/π) (taking the positive root for R ≥ 0).
A = πRh + 2πRh = 3πRh.
Now solve for R (assuming h ≠ 0):
R = A / (3πh).
If you meant A = πR^2 + 2πRh (the cylinder surface area), the solution for R is from the quadratic
πR^2 + 2πhR − A = 0, giving
R = −h + sqrt(h^2 + A/π) (taking the positive root for R ≥ 0).
