Answer:

Step-by-step explanation:

volume of cylinder = h*pi*r^2

h = 35

delta of pipe thickness = 28-24 = 4

35(pi * 4^2)

=560pi cm^3

diro101: =1759.29 cm^3(0.6g/1cm^3) => 1055.8 g

diro101: **edit** delta radius is 2...V= π(r^2 )(h) = π(2^2) (35) = 439.8 cubic cm

diro101: 439.8 cm^3(0.9g/1cm^3) => 395.82 g

moni1448: thanks but the ans. is wrong....

diro101: what weight measurement is the question looking for? g or kg?

moni1448: kg
