    function main() {
    // Write your code here. Read input using 'readLine()' and print output using 'console.log()'.
    const PI = Math.PI;
    let r = readLine()
    // Print the area of the circle:
     const pis = Math.pow(r,2);
     let ac = PI * pis;
     console.log(ac);
    // Print the perimeter of the circle:
     let pc = 2*PI * r;
     console.log(pc);``
