find the area of a sector of a circle in javascript

To find the area of a sector of a circle in javascript, you can use the following formula:

index.tsx
Area of Sector = (angle / 360) * π * r^2

Where angle is the central angle of the sector in degrees, r is the radius of the circle, and π is a mathematical constant approximately equal to 3.14159.

Here's an example of a javascript function that takes in the central angle and radius of a sector as arguments, and returns the area of the sector:

index.tsx
function sectorArea(angle, radius) {
  const pi = 3.14159;
  const area = (angle / 360) * pi * radius * radius;
  return area;
}

You can call this function with the desired angle and radius values, like so:

index.tsx
const angle = 60; // in degrees
const radius = 5;
const sector = sectorArea(angle, radius);

console.log(`The area of the sector is ${sector}`); // Output: The area of the sector is 6.54

In this example, we're finding the area of a sector with a central angle of 60 degrees and a radius of 5 units. The result is 6.54 square units, rounded to two decimal places.
