Answer:

4222.85cm³

Step-by-step explanation:

Inner diameter of the tube = 5.8cm, radius = 2.9cm

length = 1120cm

Thickness everywhere = 2mm = 0.2cm

Unknown:

Volume of the metal = ?

Solution:

To solve this, use the expression below;

   Volume  = [tex]\pi( R^{2} - r^{2} ) h[/tex]

R is the outer radius = 2.9 + 0.2 = 3.1cm

r is the inner radius = 2.9cm

h is the length

input the parameters and solve;

    Volume  = 3.142 (3.1² - 2.9²)1120

                    = 3.142 x 1.2 x 1120

                    = 4222.85cm³
