Sometimes you want to take out the area of circle,rectangle,sphere and triangle

Here i will tell you how

Circle

function areaOfCircle(radius) { return Math.PI * Math.pow(radius, 2); }

Rectangle

function areaOfRectangle(width, height) { return width * height; }

Sphere

function areaOfSphere(radius) { return 4 * Math.PI * (Math.pow(radius, 2)); }

Triangle

function areaOfTriangle(baseWidth, height) { return baseWidth * height / 2; }
