Answer:
Step-by-step explanation:
Ur question is incomplete ur question doesn't contain the height of the cylinder
Heres the answer for ur question
Just put the value for the height and ull get the answer
Inner radius 7m=700cm
Height of the pipe is not given
Thicknes is 1m=100cm
So the outer radius thats is including the thickness is 8m
Therefore the volume of the hollow cylinder is πh(R²-r²)
22/7*h(800²-700²)
22/7*h(6400-4900
22/7*h(1500)
330/7*h cm³
Now we need the mass of the pipe
That is 8*330/7*h
2640/7*h grams
Thank you
