Step-by-step explanation:

Step 1: Define

A = 2πrh + 2πr²

Step 2: Solve for h

  1. [Subtraction Property of Equality] Subtract 2πr² on both sides:                 A - 2πr² = 2πrh
  2. [Division Property of Equality] Divide 2πr on both sides:                            (A - 2πr²)/(2πr) = h
  3. Rewrite/Rearrange:                                                                                        h = (A - 2πr²)/(2πr)
