Circle (EntityTopic, 15)
From Hi.gher. Space
A circle refers to the surface of a perfectly symmetrical planar object.
Sometimes, the word circle is used to refer to the edge, while the filled in version is called a disc.
r ⇒ radius of circle
- All points (x, y) that lie on the surface of a circle will satisfy the following equation:
x2 + y2 = r2
- The hypervolumes of a circle are given by:
total edge length = 2πr
area = πr2
[!x,!y] ⇒ digon of length (rcos(πn/2))
Any unstated homology group is the trivial group 0.
- 1-frame (circle)
- H0 = ℤ, H1 = ℤ
- 2-frame (disc)
- H0 = ℤ
