50 PRINT A

Line 10: Clears the screen. CLS is used to clear the screen.
Line 20: Take the radius as input from the user. To take input, INPUT statement is used.
Line 30: Calculates the area and store the result in variable named - 'A'.
Line 40: Display the MESSAGE that - "Area of the TRIANGLE is: ". To display message, the print statement is used.
Line 50: Display the area.
Line 60: Ends the program. To end the program, END statement is used.
