(With all due respect)
Assuming:
1. That the above mentioned is a tube, and 24" refers to the outer diameter
2. That the "area" in question is if the tube was sliced from top to bottom and laid out flat, forming an oblong shape..... (therefore not the volume of the tube)
The area is the circumference of the tube x the length of the tube.
Circumference = 24" x pi = 24 x 3.14159 = 75.40" (1.915 m)
Length of tube = 12 m
Therefore metric area of tube = 1.915 x 12 = 22. 98 sq. m
Or in Imperial:
75.4 divided by 12 = 6.28 ft.
12m converted to feet = 39.37 ft.
Area of tube = 6.28 x 39.37 = 247.24 sq. ft.
Surface area of the pipe: diameter*pi*length but make sure that the diameter and length are both in meters or inches.
Measure the length of the pipe and the inner Dia of the pipe. 2 x pi x Radius x length is the inner surface area
no differnece
one inch is one inch; one inch dia refers to one inch diameter of a circle; it is still one inch
Inch dia = Number of weld joints X Size of the pipe
Surface area of the pipe: diameter*pi*length but make sure that the diameter and length are both in meters or inches.

(bigger dia - smaller dia)/2*taper length
one inch is one inch; one inch dia refers to one inch diameter of a circle; it is still one inch
Area of 25mm dia multiply by length 6000mm multiply by density mins area of 21mm dia multiply by length 6000mm multiply by density.
Inch dia = Number of weld joints X Size of the pipe
Area = πr2 = 0.25*πd2 = 0.25*π122 = 36*π = 113.0973 sq inches
The meaning of dia inch is the number of weld joints multiplied by the dia of a given pipe size, since the weld joints is on the 6" pipe, the calculations should be 1 weld x 6" = 6 dia inch.
standard rates of pipe fabrication per inch dia
A 12-inch circle has an area of 0.784 square feet.
0.152 meters.
