Question

which of the following are parts of a circles circumference?
a. diameter
b. radius
c. arc
d. center point

Explanation:

• Diameter: It is a straight - line segment passing through the center of the circle, connecting two points on the circle. It is a linear measure related to the circle's size but not a part of the circumference.
• Radius: A line segment from the center of the circle to a point on the circle. It is a linear measure (half of the diameter) and not a part of the circumference.
• Arc: An arc is a part of the circumference of a circle. For example, a semicircle is an arc that is half of the circumference.
• Center Point: It is a single point inside the circle that is equidistant from all points on the circumference. It is not a part of the circumference.

Answer:

C. Arc
