Question

The length of metal pipe is 70cm, diameter of inside is 10cm and thickness of metal is 5mm. If density of metal is 8gm/cm^3 than find mass of metal​

Answer 1

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
