Answer:
Volume Of Material Of Pipe = 2,772 m³ if 14 m long & inetrnal & External Diameter are 2 m & 16 m respectively
Step-by-step explanation:
External Diameter = 16 m
External Radius R = 16/2 = 8 m
Internal Diameter = 2 m
Internal Radius r = 2/2 = 1 m
Height = length = h = 14 m
Volume Of Material Of Pipe = π (R² - r²) * h
= (22/7) ( 8² - 1²) * 14
= 44 * 63
= 2,772 m³
Volume Of Material Of Pipe = 2,772 m³
