Answer:45760 cm^3
Step-by-step explanation:
Internal diameter of the pipe=50cm
Internal radius(r)=internal diameter/2
=50/2=25cm
Width of the pipe=2cm
External radius=internal radius + width
=25+2=27cm
Length of the pipe (h)=140 cm
Volume of the pipe=πh(R^2-r^2) cu.units
=22/7×140(27×27-25×25)
=22×20(729-625)
=440×104
=45760 cm^3
