internal diameter is 50 cm
length of pipe h is 140 cm
internal radius r2is 50/2=25cm
thickness =2cm
outer radius r1 =25+2=27cm
volume = 22/7×140{(27)^2-(25)^2}
=22/7×140×(729-625)
=22×20×104
=45760 cm^3

Given
internal diameter = 50 cm
length of pipe (height) = 140 cm
the pipe is made up of 2 cm thick iron
so,
the external diameter = 50 + 2 + 2 = 54 cm
radius = diameter ÷ 2
Internal radius (of internal diameter) = 50 ÷ 2
= 25cm.
External radius (of external diameter) = 54 ÷ 2
= 27 cm.
Volume of whole pipe (with the volume of iron) of external radius =
=
volume of empty space inside the pipe
of internal radius
=
now volume of iron in it
= volume of whole pipe - volume of empty space inside
= 320760 - 275000
= 45760
