Brass tube

The outer perimeter of brass tube (ρ = 8.5 g/cm3) is 38 cm. Its mass is 5 kg, length 54 cm. What is the pipe wall thickness?

Correct answer:

h =  2.938 mm

Step-by-step explanation:

o=2πr r=38/(2π)=6.048cm V=m/ρ=588.235 cm3 (πr2π(rh)2)54=V r2(rh)2=V/π/54 (rh)2=V/πr2 (rh)2=r2V/π/54 rh=33.111 rh=5.754 h=(6.0485.754) cm=2.938 mm
