Question

14 M long cylindrical pipe has been used for railing of the balcony diameter of the pipe is 4 cm find the weight of the pipe the balcony has to bear if the metal used for the pipe 0.25 kg per centimetre cube

Answer 1

Answer:

4400 kg.

Step-by-step explanation:

Given that Length of pipe = h = 14m = 1400 cm

Radius of pipe = diameter/2 = 4 / 2 = 2 cm

Volume of the pipe = volume of cylinder = πr²h

= 22*2*2*1400/7 = 17600 cm³

It is given that density of metal used = 0.25kg/cubic cm.

(1 cubic centimeter weight = 0.25 kg.)

Total weight = volume * density

17600 cubic centimeter weight = 17600 * 0.25 = 4400 kg.

The weight of the cylindrical pipe is 4400 kg.
