Detailed Solution

Concept: The diameter and radius is equal to 2cm and 1cm respectively. The radius of a circle is determined by dividing its diameter in half.
The diameter of a circle is equal to its whole breadth, but the radius is the distance from any point on its circumference to its center.
We must first swap out the provided value for the circumference in the circumference formula in order to obtain the radius and then the diameter of the circle in this problem.
The formula provides the circle's circumference.

So the radius of the circle we get is

Now that we are aware that a circle's radius is equal to half its diameter, we may write

We can express the diameter of the circle as since we already know the value of the circle's radius.
d=2r

Hence, the diameter of the circle,

radius of the circle,
