find the volume of a regular polygon circumscribed around a pyramid in typescript

To find the volume of a regular pyramid, we need to know the number of sides of the polygon (n), the radius of the circumscribed circle (r), and the height of the pyramid (h).

The formula for the volume of a regular pyramid is:

index.ts
V = (1/3) * (base area) * h

where base area = (n * r^2 * sin((360/n) * pi/180))/2.

So, the TypeScript code to find the volume of a regular polygon circumscribed around a pyramid will look like this:

index.ts
function findVolumeOfRegularPyramid(n: number, r: number, h: number): number {
  const baseArea: number = (n * r * r * Math.sin((360 / n) * Math.PI / 180))/2;
  const volume: number = (1/3) * baseArea * h;
  return volume;
}

6 lines

Here, n, r, and h are the input parameters that we need to pass into the function. The function then calculates the base area and volume using the formula mentioned above and returns the volume.
