find the volume of a regular polygon inscribed in a cone in ruby

To find the volume of a regular polygon inscribed in a cone, we can follow these steps:

  1. Find the apothem of the polygon. This is the distance from the center of the polygon to the midpoint of one of its sides.
  2. Find the slant height of the cone. This is the distance from the apex of the cone to any point on its base.
  3. Find the height of the cone. This is the distance from the apex of the cone to the centroid of the polygon.
  4. Use the formula for the volume of a pyramid to find the volume of the cone with the same base and height as the polygon.
  5. Multiply the volume by the number of sides of the polygon.

Here's the code in Ruby:

main.rb
# Define the number of sides of the polygon
num_sides = 6

# Define the radius and height of the cone
radius = 5
height = 10

# Find the apothem of the polygon
apothem = radius * Math.sin(Math::PI / num_sides)

# Find the slant height of the cone
slant_height = Math.sqrt(radius**2 + height**2)

# Find the height of the cone
centroid_height = (2/3.0) * apothem

# Find the volume of the cone
cone_volume = (1/3.0) * Math::PI * radius**2 * height

# Find the volume of the polygon inscribed in the cone
polygon_volume = cone_volume * num_sides / 3.0

puts "The volume of a regular polygon with #{num_sides} sides inscribed in a cone with radius #{radius} and height #{height} is #{polygon_volume}."
