The internal diameter of the tube can be found by subtracting twice the thickness from the external diameter:
Internal diameter = 18 cm - 2(4 cm) = 10 cm
The radius of the tube can be found by dividing the diameter by 2:
Radius = 10 cm / 2 = 5 cm
The volume of the plastic can be found by subtracting the volume of the hollow portion from the volume of the entire cylinder:
Volume of entire cylinder = πr^2h = π(5 cm)^2(59 cm) ≈ 14726.9 cm^3
Volume of hollow portion = π(5 cm + 4 cm)^2(59 cm) - π(5 cm)^2(59 cm) ≈ 4346.6 cm^3
Volume of plastic = Volume of entire cylinder - Volume of hollow portion ≈ 10380.3 cm^3
Therefore, the volume of the plastic is approximately 10380 cm^3.
Internal diameter = 18 cm - 2(4 cm) = 10 cm
The radius of the tube can be found by dividing the diameter by 2:
Radius = 10 cm / 2 = 5 cm
The volume of the plastic can be found by subtracting the volume of the hollow portion from the volume of the entire cylinder:

Volume of hollow portion = π(5 cm + 4 cm)^2(59 cm) - π(5 cm)^2(59 cm) ≈ 4346.6 cm^3
Volume of plastic = Volume of entire cylinder - Volume of hollow portion ≈ 10380.3 cm^3
Therefore, the volume of the plastic is approximately 10380 cm^3.
