Answer:
Solution:-
The external diameter of the pipe = 8 cm
The internal diameter of the pipe = 6 cm
External radius = 4 cm and it is denoted as 'R'
Internal diameter = 3 cm and it is denoted as 'r'
Length or height of the pipe = 2.1 m or 210 cm
Volume of the metal = Outer volume of pipe - Inner volume of pipe
= πR²h - πr²h
= (22/7*4²*210) - (22/7*3²*210)
10560 - 5940
Volume of the metal = 4620 cm³
