Subject: Need someone who can help

Hello

Please, can someone help me with this problem. I am really stuck. Can't
find my problem. Simple code snippet is not working at all. I totally
desperate.

Look at this:
--------------------start
#!/usr/bin/env ruby

class AreaOfCircle

PI = 3.14159265

  def initialize(radius, area)
    @radius = radius
    @area = area
  end

  def calc_area(radius)
    @area = PI * @radius**2
  end
end

print 'Enter radius of circle: '
keyboard_input = gets
radius = keyboard_input.to_f

instance = AreaOfCircle.new
screen_output = instance.calc_area(keyboard_input)
puts screen_output
----------------------------------- end

I'm already pulling my hairs (not much left by now). Hopefully you can
give me any hint!

Regards,
Baiki
