Mathematically, we can calculate the outer area of a hollow cylinder by multiplying pie, times the outer diameter of the circle, times it’s height. In the example below, the hollow cylinder has no thickness, but when dealing with real pipes in the ship yard, you would measure the outer diameter of the pipe for this purpose. We will look at this in more detail in following lessons.
Area of a Hollow Cylinder (no caps)
The area of a hollow cylinder is given by the formula mentioned below:
•Area of a Hollow Cylinder =π∗d∗h
Where,
π (sounds like ‘pie’) is 3.1416
d is the diameter of the cylinder
H is the height of the cylinder
