Height of Pipe=22 CM
Diameter =20CM
,',Radius =10CM
Volume of Pipe= πr^2h
=22/7×(10)^2×22
48400/7CM^2
Weight= 9gm/cm^3×48400/7cm^3
=(48400×9)/7 gm
=435600/7 gm
=62228.57 gm
=62.22kg

length of pipe = 22cm
diameter = 20cm
radius = 20/2 = 10cm
volume of pipe = pie r^2h = 22/7×(10)^2×22 = 22/7×100×22 = 48400/7 = 6914.28cm^3
weight of pipe = 6914.38×9 = 62228.52g = 62.22kg
diameter = 20cm
radius = 20/2 = 10cm
