Answer:

C=4\pi

Step-by-step 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\times D, where, D represents diameter of circle.

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

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

\text{Circumference of circle}=4\pi

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