find the volume of a cylinder in javascript

To find the volume of a cylinder, we can use the formula V = πr²h, where V is the volume, r is the radius of the cylinder, and h is the height of the cylinder.

Here's the code to find the volume of a cylinder in JavaScript:

index.tsx
// function to calculate the volume of a cylinder
function getCylinderVolume(radius, height) {
  const pi = Math.PI;
  const volume = pi * radius ** 2 * height;
  return volume;
}

// example usage
const radius = 5;
const height = 10;
const volume = getCylinderVolume(radius, height);
console.log("The volume of the cylinder is " + volume);

In this code, we define a function getCylinderVolume that takes in two parameters, radius and height. We then define the constant pi as Math.PI, which is the mathematical constant representing pi.

We then calculate the volume using the formula V = πr²h, and return the result.

Finally, we provide an example usage of the function, where we define the radius and height of a cylinder, and then call the getCylinderVolume function to get the volume. The result is logged to the console.
