Need help with these scenarios

Question 1

Write a JavaScript program to get the volume of a Cylinder with four decimal places using object classes. Volume of a cylinder : V = πr2h where r is the radius and h is the height of the cylinder.

Your solution must include an HTML and a JavaScript file, with a button to create the cylinder, inputs for the cylinder's radius and height and an output to show the cyclinder's volume.

Your solution must also use an object for the cylinder, a constructor for passing the radius and height, and a getter for returning the volume.

Question 2

Write a JavaScript program to display the reading status (i.e. display book name, author name and reading status) of the following books.

Question 3

Write a JavaScript function to parse an URL. Your solution must use

var a = document.createElement('a');

for( i = 0; i < queries.length; i++ ) {
split = queries[i].split('=');
