    const PI = Math.PI

    // Write your code here. Read input using 'readLine()' and print output using 'console.log()'.
const input = readLine()

// Print the area of the circle:
const circleArea = PI * input**2
console.log(circleArea)


// Print the perimeter of the circle:
const circlePerimeter = 2 * PI * input
console.log(circlePerimeter)
