Answer:
The total radiating surface is approximately 2.2 m^2
Step-by-step explanation:
Here, we want to get the total surface area of the cylindrical pipe
Firstly, we need the measurements to be uniform
If length is m, then diameter should be in meters too
That would be 5/100 = 0.05 m
Radius is half of the diameter
Mathematically, that’s 0.05/2 = 0.025 m
The formula for the total surface area is;
A = 2 * pi * r^2 + 2 * pi * r * h
A = (2 * 3.142 * 0.025^2) + (2 * 3.142 * 0.025 * 14)
A = 0.0039275 + 2.1994 =2.2033275
This is approximately 2.2 m^2
