Question

A metal pipe is 14 m long if its internal and external diameters are 2 m and 16 m respectively then find volume of pipe​

Answer 1

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

Answer 2

Answer:

2772m^3

height=14m

External radius(R) =16/2=8m

internal radius(r) =2/2=1m

Step-by-step explanation:

volume of the metal pipe=π(R^2-r^2)×h

=22/7×(8^2-1^2)×14

=44×63

=2772m^3
