Answer:
2 units
Step-by-step explanation:
If given the radius, [tex]r[/tex], of a circle, we can easily find the diameter. Consider this:
Every circle has a center. We may draw a line from this center to any point on the circle. This line will represent our radius.
Now, we may continue this line to another edge of[tex]c=2r[/tex] the circle. If this line does not bend, then it represents our circumference.
That is all the circumference is: a straight line from one point on a circle to another, passing through the center of our circle. This can be thought of as two radii.
Therefore, [tex]c=2r[/tex].
