Answer:
We can find volume of wooden pipe by subtract volume of inner radius cylinder from volume of outer radius cylinder
Step-by-step explanation:
Radius of outer cylinder = 28/2 cm= 14 cm
Radius of inner cylinder = 24/2 cm= 12 cm
height of cylinder = 35 cm
Volume of wooden pipe = volume of outer radius cylinder - volume of inner radius cylinder
= πR^2h - πr^2h
=πh(R^2 - r^2)
= 22/7 *35(14^2 -12^2)
=110(52)
= 5720 cm^3
since,
mass of 1 cm^3= 0.6g
therefore ,
mass of 5720 cm^3 = 5720*0.6 g
= 3432g
= 3.432 kg
