Calculate the approximate mass of the steel pipe. length of pipe = 4m. inside radius =130mm. outside radius = 150mm

555.936 kg

Explanation:

h = Length of pipe = 4 m

r = Inside radius =130 mm

R = Outside radius = 150mm

Volume of the cylinder

v = πR²h - πr²h

⇒v = πh(R²-r²)

⇒v = π4(0.15²-0.13²)

⇒v = 0.0704 m³

Density of steel varies between 7,750 and 8,050 kg/m³

So, let us take the average of the two values so we get density of steel as 7900 kg/m³ as the exact density is not given

Density

So, approximate mass of the steel pipe is 555.936 kg
