If I understand your question correctly, you would need to subtract the area of the inscribed circle from the circumscribed circle. Which would approximately be 78.60cm squared.
sectorsThis 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 distance around a circular region is called circumference
The union of a circle and its interior refers to the combination of all points on the circle itself and all points inside the circle. This forms a set that includes both the boundary of the circle and its interior region. In mathematical terms, this union is represented as the circle itself along with all points within the circle, denoted as the closed disk.
That depends on what area you choose to shade.

No. A sector is bounded by part two radii and part of the circumference.
A sector of a circle would fit the given description
It is called a sector.
Circular Ring Sector.
The region bounded by an arc and two radii to the arc's endpoints is known as a sector of a circle. It resembles a "slice" of the circle, with the arc serving as the curved edge and the two radii as the straight edges extending from the center of the circle to the endpoints of the arc. The area of this sector can be calculated based on the angle subtended by the arc at the center and the radius of the circle.
The region bounded by an arc and a chord is known as a "segment" of a circle. This segment includes the area enclosed by the chord and the arc connecting the endpoints of the chord. The segment can vary in size depending on the length of the chord and the curvature of the arc. If the chord is a diameter, the segment is known as a semicircle.
A bounded region refers to a region in a coordinate plane that can be contained within a finite area and can be enclosed by a finite number of points or curves. In other words, a bounded region has a definite boundary that does not extend infinitely in any direction.

An arc is a portion of the circumference of a circle, defined by two endpoints on the circle. In contrast, a sector is a region enclosed by two radii and the arc connecting them, resembling a "slice" of the circle. Essentially, while an arc is just the curved line, a sector includes the area bounded by the arc and the radii.
