Plastic pipe

Calculate the plastic pipe's weight with diameter d = 70 mm and length 380 cm if the wall thickness is 4 mm and the density of plastic is 1367 kg/m3.

Correct answer:

m =  4.3 kg

Step-by-step explanation:

r1=d/2=35 mm r2=r14=31 mm V=V1V2=πr12lπr22l V=πl(r12r22)=3151.65 mm3 m=ρV=1367kg/m33151.65 mm3=4.3 kg
