Program/Source Code:

The source code to calculate the area of the circle is given below. The given program is compiled and executed successfully.

// Golang program to calculate the area of the circle

package main
import "fmt"

func main() {
    var radius float32=0
    var area float32=0
    
    fmt.Printf("Enter radius: ")
    fmt.Scanf("%f",&radius)
    
    area = 3.14 * radius * radius

    fmt.Printf("Area of Circle: %f",area)
}

Output:

Enter radius: 5.2
Area of Circle: 84.905594

Explanation:

In the above program, we declare the package main. The main package is used to tell the Go language compiler that the package must be compiled and produced the executable file. Here, we imported the fmt package that includes the files of package fmt then we can use a function related to the fmt package.

The main() function is the entry point for the program. In the main() function, we read the radius from the user and calculated the area of the circle using the standard formula. After that printed the result on the console screen.
