H=14cm given

R(outer radius)=10cm
r (inner radius)=10-2=8cm
that r^2 means r raise to power 2

volume of pipe= π R^2 h - π r^2 h
=πh(R^2 - r^2)
=22/7 * 14(10^2 - 8^2)
=22*2(100-64)
=44(36)
=1584 cm^3

density=10g/cm^3
mass/volume=10
mass=10*volume
mass=10*1584
mass=15840g
hope it will help u pls mark this as brainliest answer
