Find the mass...

Question

Find the mass of a 3.5 m long lead pipe, if the external diameter of the pipe is 2.4 cm, thickness of the metal is 2 mm and the mass of 1 cm³ of lead is 11.4 grams.

Open in App

Solution

Length of the pipe (h) = 3.5 cm = 300 cm

External radius of the pipe (R) = $\frac{2.4}{2} = 1.2 c m$

Mass of 1 cm³ pipe is 11.4 gm

Total mass = 4184 × 11.4 = 5517.6 gm = 5.518 kg.
