let currentLine = 0;

process.stdin.on("data", (inputStdin) => {

inputString += inputStdin;

});

process.stdin.on("end", (_) => {

inputString = inputString.trim().split("\n").map((str) => str.trim());

main();

});

function readLine() {

return inputString[currentLine++];

}

/* Please do not modify anything above this line */

function Circle(radius) {

/* Write your code here */

}

/* Please do not modify anything below this line */

function main() {

Answer 1

process.stdin.resume();
process.stdin.setEncoding("utf-8");


let inputString = "";
let currentLine = 0;


process.stdin.on("data", (inputStdin) => {
    inputString += inputStdin;
});


process.stdin.on("end", (_) => {
    inputString = inputString.trim().split("\n").map((str) => str.trim());
    main();
});


function readLine() {
    return inputString[currentLine++];
}


/* Please do not modify anything above this line */


function Circle(radius) {
    return {
        getArea: function() {
            return Math.PI * radius * radius;
        },
        getCircumference: function() {
            return 2 * Math.PI * radius;
        }
    }
}


/* Please do not modify anything below this line */
function main() {
    const radius = JSON.parse(readLine());
    const circle1 = new Circle(radius);
    
    console.log(circle1.getArea());
    console.log(circle1.getCircumference());
}
