A pipe of thickness 3/4cm has an internal diameter of 14cm. Find the volume of material of 3m of pipe in cm cubed.
-----------
OD = 15.5 cm --> r = 7.75 cm
Inside r = 7 cm
Cross-section area = pi*(7.75^2 - 7^2) = 11.0625pi sq cm
---
Vol = area*length = 11.0625*3000*pi = 33187.5*pi cc
=~ 104261.6 cc
