Problem Solution:

Here, we will read the radius of the circle from the user and calculate the perimeter of the circle. After that, we will print the result on the console screen.

Program/Source Code:

The source code to calculate the perimeter of the circle is given below. The given program is compiled and executed on the ubuntu 18.04 operating system successfully.

```// Scala program to calculate the perimeter of circle

object Sample{
def main(args:Array[String]){
var perimeter:Float=0

//Caculate the perimeter of circle
perimeter = 2 * 3.14F * radius

println("Perimeter of circle: "+perimeter)
}
}
```

Output:

```Enter radius: 4.2
Perimeter of circle: 26.376
```

Explanation:

In the above program, we used an object-oriented approach to create the program. Here, we created an object Sample. We defined main() function. The main() function is the entry point for the program.

In the main() function, we created two float variables radius, perimeter that are initialized with 0. Then we read the value of radius from the user and calculate the perimeter of the circle. After that, we printed the result on the console screen.
