Answer:

  r = √(V/(πh))

Step-by-step explanation:

To solve for r, "undo" what has been done to r. The "undo" is generally in the reverse order. Here, we have ...

  • r is squared
  • the square is multiplied by πh

To undo these operations, we ...

  V/(πh) = r² . . . . . . . . divide by πh

  √(V/(πh)) = r . . . . . . take the square root

  r = √(V/(πh))
