Question

the point equidistant from all points on the circle is called the __________. the formula c = 2πr is used to find the ________ of a circle. a line segment with both endpoints on the circle is called a ________. the area of a circle can be found using the formula a = π×r², where r is the ________. a sector of a circle is bounded by two ________ and an arc. the angle formed by two radii of a circle is called the __________ angle.

Explanation:

1. By definition, the center of a circle is equidistant from all points on the circle.
2. The formula $C = 2\pi r$ calculates the circumference of a circle.
3. A line - segment with both endpoints on the circle is a chord.
4. In the area formula $A=\pi r^{2}$, $r$ represents the radius of the circle.
5. A sector of a circle is bounded by two radii and an arc.
6. The angle formed by two radii of a circle is the central angle.

Answer:

1. Center
2. Circumference
3. Chord
4. Radius
5. Radii
6. Central
