    S = 2πrh + 2πr²

    We factor:

    S = 2πr (h + r)

    S/2πr = h + r

    (S/2πr) - r = h

    Let us assume:

    S = 1000

    r = 10

    π = 3.14

    S = 2πrh + 2πr²

    1000 = (2 * 3.14 * 10 * h) + (2*3.14*10²)

    1000 = 62.80h + 628

    1000 - 628 = 62.80h

    372 = 62.80h

    372/62.80 = h

    5.92 = h

    Let us use the derived formula to check if it is correct:

    h = S/2πr - r

    h = (1000 / (2*3.14*10)) - 10

    h = (1000/62.80) - 10

    h = 15.92 - 10

    h = 5.92
