#. In a hot water heating system, there is a cylindrical pipe of length 14 m and diameter 5 cm. Find the total radiating surface in the system.

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

the central idea is that:

individuals should refuse to cooperate with institutions they believe unjust.

thoreau felt  that governments were more often agents of corruption than justice, even democracies, and that just because the majority feels a certain way does not make it just or correct in absolute terms. he uses the fact that slavery exists in our democracy to support this idea.

he goes on to say that, as a result, people should live true to their own internal laws regarding right and wrong, as a product of reflection and a moral life, rather than following every law that society imposes.
