A cylindrical tube, open at both ends, is made of metal. The internal diameter of the tube is 10.4 cm and its length is 25 cm. The thickness of the metal is 8 mm everywhere. Calculate the volume of the metal.

Question

Philoid · Accepted Answer

Given,

Internal diameter of tube = 10.4 cm

So radius of tube =

Length of tube = 25 cm

Thickness of metal of tube = 8 mm =

Hence , external radius of tube = 5.2+.8 = 6 cm

So, volume of metal = π(R² – r²)h =
