Question

Area and Circumference of a Circle

Given radius 

radius of a circle, write a JS constructor function with the methods getArea and getCircumference to calculate the area and circumference of the circle.

Note
The value of π = 3.14
Quick Tip

Use the formulae to calculate,

Area of circle = π * radius * radius
Circumference of circle = 2 * π * radius
Input
The input will be a single line containing a number radius
Output
The first line of output should contain the area of the circle
The second line of output should contain the circumference of the circle
Sample Input 1
7
Sample Output 1
153.86
43.96

Sample Input 2
25
Sample Output 2
1962.5
157

Answer 1

function AreaCircumference(radius) {
    this.radius = radius;

    this.getArea = () => 3.14 * this.radius ** 2;

    this.getCircumference  = () => 2 * 3.14 * this.radius;

    console.log(this.getArea());
    console.log(this.getCircumference());
}

const radius1 = new AreaCircumference(7);
const radius2 = new AreaCircumference(25);
