Um die Oberfläche eines kugelförmigen Behälters zu berechnen, können wir die Formel für die Oberfläche einer Kugel verwenden:
A = 4\pi r^2

Gegeben:
Durchmesser, d = 49 m

Wir können den Radius (r) berechnen, da r = \frac{d}{2}:
r = \frac{49}{2} = 24.5 \text{ m}

Nun können wir die Formel für die Oberfläche verwenden:
A = 4\pi \times (24.5)^2

A = 4\pi \times 24.5^2

A = 4\pi \times 600.25

A \approx 2401.00 \text{ m}^2

Antwort: Bei der Herstellung des kugelförmigen Gasbehälters wurden mindestens 2401.00 \, \text{m}^2 Stahlblech verarbeitet.
