Answer:
[tex]C=4\pi[/tex]
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.
[tex]\text{Circumference of circle}=\pi\times D[/tex], where, D represents diameter of circle.
Upon substituting the measure of diameter in above formula we will get,
[tex]\text{Circumference of circle}=\pi\times 4[/tex]
[tex]\text{Circumference of circle}=4\pi[/tex]
Therefore, the circumference of our given circle would be [tex]4\pi[/tex].
