This actually isn't such a weird question, but you're probably too young to remember. In the 1970s and early 1980s, we didn't have CDs or DVDs, just records. They used to put records on the back of cereal boxes, and they used to put records in magazines. The records in magazines were called Soundsheets. When you got one, it was this thin piece of black plastic with record grooves on one side. You tore it out of the magazine and played it. The records on cereal boxes were stuck onto the back of the box; to play one you cut it out of the back of the box, punched a hole in the middle and put it on your turntable. Both of these discs were square. So the answer to "what does a square disc do?" is "the same thing as a round one."

Disc most closely describes

Area of disc: pi*6^2 = 36*pi square cm

The area of a disc of radius R units is pi*r^2 square units.

Surface area in square units = pi*radius2

Pi*6 * * * * * Independent of the radius? Makes no difference if the disc is twice as wide? I think not! It is actually 2*pi*r2 where r is the radius of the disc.
