Circles
Circumference is the distance around a circle.
Diameter is a line segment whose endpoints are on the circle and pass through the center.
A radius is a line segment that goes from the center point to a point on the circle.
A chord is a line segment whose endpoints are on the circle.

Prisms and Cylindars
A prism is a polyhedron in which two of the faces are congruent polygons in parallel planes.
These two faces are called the bases of the prism.
These two faces are called the bases of the prism.
