find the volume of a regular polygon circumscribed around a cylinder in ruby

To find the volume of a regular polygon circumscribed around a cylinder, we need to:

  1. Find the height of the cylinder (which is also the height of the regular polygon).
  2. Find the length of a side of the regular polygon (which is also the diameter of the cylinder).
  3. Use these dimensions to calculate the volume of the cylinder with the formula:
    main.rb
    volume = Math::PI * radius**2 * height

Here's the code in Ruby:

main.rb
def volume_of_regular_polygon_circumscribed_around_cylinder(num_sides, side_length, height)
  radius = side_length / 2
  volume = Math::PI * radius**2 * height
  return volume
end

In this code, num_sides represents the number of sides of the regular polygon, side_length represents the length of a side of the polygon, and height represents the height of the cylinder (which is also the height of the polygon).

You can call this method by passing in the appropriate values for these parameters:

main.rb
volume = volume_of_regular_polygon_circumscribed_around_cylinder(6, 10, 20)
puts "The volume of the regular hexagonal prism is #{volume}"
