To calculate the JavaScript Program to Find the Volume of the Cylinder. We use the direct formula to calculate the volume of the cylinder. A cylinder is a three-dimensional geometric shape that consists of two parallel circular bases connected by a curved surface.

Example:

V = πr^2h
where,
π is constant, value 3.141592653589793
h is height of cylinder 
r is radius of cylinder

Approach

• The code defines a function cylinderVolume that takes two parameters “radius” and “height”.
• Inside the function, it calculates the volume of a cylinder using the formula “V = πr^2h”, where “r” is the radius and “h” is the height.
• The Math. pow() function is used to calculate the square of the radius.
• It then assigns the result to the variable “volume” and returns it.
• Finally, the code calculates the volume of a cylinder with a given radius and height and logs the result to the console.

Example: JavaScript program to find the volume of a cylinder.

// Using formula

function cylinderVolume(radius, height) {

    let volume = Math.PI * Math.pow(radius, 2)
                         * height;
    return volume;
}

// Radius of the cylinder
let radius = 5;

// Height of the cylinder
let height = 10;

let volume = cylinderVolume(radius, height);
console.log("Volume of the cylinder is :", volume);

Volume of the cylinder is : 785.3981633974483
