Answer to Question #261446 in HTML/JavaScript Web Application for swsq

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
