Answer 1

If you need to enter an integer value then use scanner.nextInt() and repeat Lesson 5.1.

double result = 6.28 * scanner.nextInt();

Answer 2

Scanner is an object and you cannot multiply object with value

Take user input using scanner object then multiply that input with pi.

scanner is not a variable name it's an object of Scanner class.

variable should have a type String, int, float or double.
