A spiral is a line, hence its area is zero.
For the area of a spiral line of given width, you've moved away from simple math.

Spin A spiral dive is just a spiral dive and should not be confused with a spin. If a pilot can not see the horizon, because of clouds for instance, he may not appreciate that he is going into a spiral dive and this can lead into a 'graveyard spiral'
A screw is an inclined plane in a spiral.
Theodorus invented this spiral.
How do calculate spiral length of Spiral rings
An ordinary spiral galaxy has spiral arms coming out of the core. In a barred galaxy, the central area consists of a bar of stars and the spiral arms are attached to the ends of the bar.
Halo is the name given for a sparse area in space that surrounds a spiral galaxy. This type of galaxy has special constellations.
The area surrounding a spiral galaxy is called it's Halo, and is a spherical region encapsulating the galaxy.

When an area of low pressure is created with strong winds that spiral towards the center, a tropical cyclone is being formed. The spiral arrangement of thunderstorms produces heavy rain.

The spiral in shape is used in many areas in Mathematics. It is usually used when dealing wit the area of the solid objects.
The spiral shape you are observing is a result of a vortex current which has formed as a result of the pressure difference inside the device and the relatively higher air pressure outside the device. The area closest to the air opening will have a higher atmospheric pressure than area further away from the opening resulting in the rising spiral you see. It is a very similar phenomena to the spiral you also see when you flush a toilet, the only difference is instead of the crap going into a sewer it goes into your lungs.
