Question

an iron pipe is 42 cm long and its exterior radius is 4 cm if the thickness of the pipe is 1 cm and iron weight 100g/cm3, the weight of the pipe is
answer it fast. some what urgent

Answer 1

height of pipe=42cm
exterior Radius of pipe=4cm
thickness of pipe=1cm
inner radius of pipe=4-1=3cm
volume of pipe =( pia×R^2×h)-pia×r^2×h)
=pia×h(R^2-r^2)
=22/7)×42[(4)^2-(3)^2]
=22×6(16-9)
=(22×6×7)cm^3
=924cm^3

weight of 1cm^3=100g
weight of iron 924cm^3=(924×100)g
=92400g
=92kg400g
