\begin{frage}[4]%% Anzahl Punkte für diese Aufgabe

  Aus einem Kupferblech der Breite $b=0.75m$ soll eine Dachrinne gebogen werden:

  
  \bbwCenterGraphic{90mm}{fct/quadratische/extremwert/img/Dachrinne.pdf}

  Das Blech wird wie in der Abbildung gebogen (oben ist die Rinne
  offen).

  Wie groß wird der Radius $r$ der Rinne, wenn möglichst viel Wasser
  darin fließen soll?

  \noTRAINER{\vspace{15mm}}

  Die Rinne wird einen Radius $r = \LoesungsRaum{0.238732 =
    \frac{b}{\pi} = \frac{0.75}{\pi} \text{m}}$
  haben (Resultat exakt oder auf mind. 4 signifikante Stellen).%
