HTML Code:

<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<title>Volume of a Cylinder</title>
</head>
<body>
</body>
</html>

JavaScript Code:

function Cylinder(cyl_height, cyl_diameter) {
  this.cyl_height = cyl_height;
  this.cyl_diameter = cyl_diameter;
}

Cylinder.prototype.Volume = function () {
  var radius = this.cyl_diameter / 2;
  return this.cyl_height * Math.PI * radius * radius;
};

var cyl = new Cylinder(7, 4);
// Volume of the cylinder with four decimal places.
console.log('volume =', cyl.Volume().toFixed(4));

Sample Output:

volume = 87.9646
