Answer:

Step-by-step explanation:

Inner radius,r=12/2=6cm

thickness=1cm

so,outer radius,R=6+1=7cm

height,h=1m=100cm

volume=pi×(R^2-r^2)×h

=22/7×(7^2-6^2)×100

=22/7×(49-36)×100

=22/7×13×100

286/7×100

=28600/7

since,density=7.7gm/cm^3

also,weight=volume×density

weight=28600/7×7.7gm

=31460gm
