Height of cylindrical pipe = Length of cylindrical pipe = 28m
Radius of circular end of pipe = diameter/ 2
= 5/2 cm = 2.5cm = 0.025m
Now, CSA of cylindrical pipe = 2πrh,
where r = radius and h = height of the cylinder
= 2 × (22/7) × 0.025 × 28 m2
= 4.4m2
The area of the radiating surface of the system is 4.4m2.
