Answer 1

Answer:

Step-by-step explanation:

The hot water heating system would have CSA as its both top and bottom are not used...

therefore formula to find its radiating area = 2 pie r h

Given :- d = 5 cm = 0.05 m

now r = d/2 = 0.05/2 = 0.025 m

therefore on applying formula..

-> 2 pie r h

-> 2 * 22/7 * 0.025 * 28

= 4.4 m^2
