Given a radius of the circle,
return the area and the circumference of the circle in 2 decimal places.
function CircleArea(r){
return Number((Math.PI*r*r).toFixed(2));
}
function CircleCir(r){
return Number((Math.PI*r*2).toFixed(2));
}// TODO: Add your tests here
// Starting from Node 10.x, [Mocha](https://mochajs.org) is used instead of our custom test framework.
// [Codewars' assertion methods](https://github.com/Codewars/codewars.com/wiki/Codewars-JavaScript-Test-Framework)
// are still available for now.
//
// For new tests, using [Chai](https://chaijs.com/) is recommended.
// You can use it by requiring:
// const assert = require("chai").assert;
// If the failure output for deep equality is truncated, `chai.config.truncateThreshold` can be adjusted.
