I must write a JavaScript function that calculates circle area by given radius. Print the area as it is calculated and then print it rounded to two decimal places.
- The input comes as a single number argument - the radius of the circle.
- The output should be printed to the console on a new line for each result.
Example:
Input: 5
Output:
78.53981633974483
78.54

My code is:
function circleArea(radius) {
let area = Math.PI * (radius * radius);
console.log(area);
console.log(Math.round(area*100)/100);
}
circleArea(5);

Two solutions from me:
function circleA(r) {
console.log(Math.PI * r * r);
console.log(Math.round(Math.PI * r * r * 100) / 100);
}
circleA(5);
function cA(rad) {
let area = Math.PI * rad * rad;
console.log(area);
let areaRounded = Math.round(area * 100) / 100;
console.log(areaRounded);
}
cA(5);
