Large cylinders occur in real life, eg gas containers.
Tin cans are cylinders.
Bins are cylinders.
Wheels are cylinders.
Suppose a large gas cylinder has to be treated with paint , we have to know the surface area in order to purchase the required volume of paint.

In sheet metal work where you need to know the width and length of a flat sheet in order to have the right size to make various types of pipe.
In any application where you want to calculate the amount of heat lost or gained through the cylinders' surface.
If one is painting a smokestack, or any other large cylinder, as an example, you want to know the surface area in order to have enough paint on hand.
You would also want to know the same figure if you were building the smokestack from bricks or even concrete. Surface are times wall thickness equals the volume of bricks or concrete you will need to order.
In making banjo bodies, you would need to know the surface area in order to cut enough sheets of thin veneer to form the laminated cylinder from.
Just a few examples.

there are a lot of application of these, such as calculating the surface area of a piston (engine), architecture and more, everything we learn is useful

Think of everything that is cylindrical from auto pistons to storage tanks.All their area needs to be known from material needs to clearances and tolerances.

You have to make a can and need to know how much metal to use.
