Answer:

Answer is 118800g=118.8kg

Step-by-step explanation:

1=42 r=4cm thickness = 1cm weight of iron

volume of cylinder= πr^2h

volume of iron pipe =π(4+1)2 42-π×4^2×42

=π×42(25-16)

=22/7×42×9=1188cm2

weight of 1cm3 iron =100g

weight of 1188cm3=1188×100=118800g

=118.8kg

hope it is helpful to you.
