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

Formula used

V = πr2h

where:

• V is volume of cylinder
• π is mathematical constant whose value is equal to 3.14
• r is radius of cylinder
• h is height of cylinder

Approach

We will create a function and pass radius and height as parameter. Calculate the volume of the cylinder using the formula. Return the calculated volume

Example: This example shows the finding the volume of cylinder using direct formula.

// program to calculate volume of cylinder

function VolumeOfCylinder(radius, height) {

    // volume of the cylinder 
    // using the formula V = πr^2h

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

Volume of the cylinder is : 785.3981633974483
