Answer:
24
Step-by-step explanation:
4!
! represents multiplying all the numbers behind
4*3*2*1=24

the length of the rope needs to be around 82.8
Answer:
31.869 kg.
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
or,31.46 kg
Divide all three sections height times width times times length and you get your answer.
