Answer:
Step-by-step explanation:
Length of metal pipe is (h)=70cm
Diameter is 10cm=radius =5cm
Thickness is 5mm=0.5cm
Therefore the inner radius is 4.5cm
Volume of cyliner is πr²h
Therefore he volume of hollow cyliner is πh(R²-r²)
22/7*7(5²-4.5²)
22*(25-20.25
22*4.75
93.5cm³
Now given that 8gm/cm³
So 8*93.5=748 gm
