Question

question 1 (5 points)
in the clock picture below line dc is an example of a what?
a radius
b diameter
c center

Explanation:

A radius is a line segment connecting the center of a circle to any point on its circumference. In the clock image, point D is the center, and point C lies on the outer edge (circumference) of the circular clock, so line DC fits this definition. A diameter spans across the circle through the center (connecting two circumference points), and the center is a single point, not a line.

Answer:

a. radius
