Subject: Simple question

I have just picked up ruby and am trying to teach my self.  so this
question is probably easy but its giving me fits.
<code>
class Test
  def round
    puts "the object is round"
  end
  def random
    $radus=rand(10)+1          <---Global Variable
  end
  def coords
    x=rand(1000)
    y=rand(1000)
    z=rand(1000)
    lo=[x,y,z]
    puts lo
  end
  def size
    pi=Math::PI
    area=pi*(radus^2)           <----error cant find radus?
    volume = 4/3*pi*(radus^3)
    puts volume
    puts radus
    puts area
  end
  def landmass
    landmass=size.area*0.33         <--- why is this wrong?
    puts landmass
  end

  t=Test.new
  puts t.landmass
end
</code>

other than my ugly code; why doesn't size see radus and landmass see
area
