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
$4\pi$ .
