Circle
A closed curve with coplanar points at the same distance from the center point
Circumscribe
To draw a figure around another, touching it at points but not cutting it.
Cylinder
a solid bounded by a cylindrical surface and two parallel planes (the bases)
Density

Diameter
The straight distance from one outside curved surface through the center point to the opposite outside curved surface
Ellipse

Inscribe
