Question

The outre diameter of a metallic pipe is 14cm and its thickness is 1cm if the density of the metal is 3g/cmcube, find the weight of 5m long pipe

Answer 1

Answer:

Step-by-step explanation:

Height of pipe is 500cm

Outer pipe radius is 7 cm

Inner pipe radius is 6cm (1cm pipe thickness)

Vol. Of pipe is outer - inner

22/7*500(49-36)

=20428.57 cm cube

Density is 3gm per cm cube

So pipe weight is

20428.57/3 =6809.5 gm

6.8095 Kg
