3a) Hohlzylinder:

Höhe: 4m – 0,1m = 3,9m

Grundfläche:

pi*(r_außen^2 – r_innen^2)

= pi*((5m)^2-(4,9m)^2) = 3,11 m^2

Volumen: Grundfläche mal Höhe

3,9m * 3,11m^2 = 12,13 m^3

Bodenplatte:

Höhe 0,1 m

Grundfläche: pi*(5m)^2 = 78,5 m^2

Volumen: 7,85 m^3

Gesamtvolumen:

7,85 m^3 + 12,13 m^3 = 19,98 m^3

b) 19,98 m^3 * 8,95 kg/m^3 = 178,85 kg
