Answer:


C=4\pi

Explanation:

We have been given that the diameter of a circle is 4 cm.

We know that circumference of circle is pi times the diameter of circle.


\text{Circumference of circle}=\pi* D, where, D represents diameter of circle.

Upon substituting the measure of diameter in above formula we will get,


\text{Circumference of circle}=\pi* 4


\text{Circumference of circle}=4\pi

Therefore, the circumference of our given circle would be
4\pi.
