Man kann den Umfang mit der folgenden Formel berechnen:
Wie lang ist die Kreislinie eines Kreises mit dem Radius 5 cm?
Rechnung: _________________________________________________________________________
Antwort: __________________________________________________________________________
Aufgabe 3
Berechne für die folgenden Längen den Kreisumfang bzw. die Länge der Kreislinie sowie die zweite fehlende Größe.
Schreibe deine Rechnung auf die nächste Seite und trage das Ergebnis hier ein.
a) d = 8 cm; r = ______________; U = ___________________
b) r = 2 cm; d = ______________; U = ___________________
c) d = 5 cm; r = ______________; U = ___________________
d) r = 9 cm; d = ______________; U = ___________________
e) d = 1 cm; r = ______________; U = ___________________
