A central angle.The section of the circle formed by that angle and the part of the circle (the part being the circumference) between the radii is called a sector.
sector
yes
the interior of a circle is called a cabret
A piece of the circumference of a circle is called an arc A piece of the area of a circle bounded by an arc and two radii is called A sector. A piece of the area of a circle bounded by an arc and a chord is called a segment
A circle in a solid is called a cross-section.
a sector
A cross section, I believe
A defined continuous section of the circumference is called an arc.
It may be called a 90 degree section , or 1 fourths of a circle.
A circle. (or approximately a circle if you look closely the mountains and valleys that the cross section cuts through disturb the circle). a mathematical sphere will give a mathematical circle at all cross sections.
no it is not, it is called a sector? I think....
The cross section of a circle is a circle. A circle is defined as a plane figure (i.e. 2 dimensional object) with a constant radius in both dimensions. Since a cross section is, by definition 2 dimensional, a circle's cross section is the circle itself.

Circle
I always called it an arc. It is simply a section of the circle. The ends are determined by the two radii you referenced. Each of the radii start at the center of the circle and end at their intersection with the circle. The portion of the circle that lies between the ends of the two radii is an arc.
