Circumference of a circle is given by −
pi * (r * r)
And area of a circle is given by −
2 * pi * r
Where r is the radius of the circle.
We are required to write a JavaScript function that takes in the radius of circle and calculates the difference between the area and the circumference of the circle
Example
Let’s write the code for this function −
const rad = 6;
const circleDifference = radius => {
const area = Math.PI * (radius * radius);
const circumference = 2 * Math.PI * radius;
const diff = Math.abs(area - circumference);
return diff;
};
console.log(circleDifference(rad));
console.log(circleDifference(5.25));
console.log(circleDifference(1));Output
The output in the console −
75.39822368615503 53.60342465187584 3.141592653589793
