This is a "sector" of the circle. We usually visualize it as a wedge of pie. But by the definition, it can be a quarter of the disk, a half of the disk, or as close to the full disk as you want, but just not the whole disk.

The area bounded by an arc of circle and two radii is known as a "circular sector"
The area is called as "Sector"
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

You can draw exactly four of the those right-angled sectors in a circle. The definition of a sector is quoted as "the portion of a circle bounded by two radii and the included arc". The circumference of a circle = 2*pi*radius. The arc of each sector will be 0.5*pi*radius.
