Circle Perimeter and Area

/*
Circle Perimeter and Area
Write a program that reads the radius r of a circle and prints its perimeter and
area formatted with 2 digits after the decimal point.


Examples:
r           perimeter           area
2           12.57               12.57
3.5         21.99               38.48

    // radius
    let pr = +input[0];
    let radius = Math.PI * pr * pr;

    console.log(radius.toFixed(2));

    // perimeter

    let perimeter = Math.PI * 2 * pr;
