Answer:

[tex]6\pi[/tex] or approximately [tex]18.85[/tex] units

Step-by-step explanation:

The formula for finding the circumference of a circle is [tex]C=2\pi r[/tex], where [tex]C[/tex] = circumference and [tex]r[/tex] = radius. In this case, [tex]r=3[/tex], so after plugging that into [tex]C=2\pi r[/tex], we get:

[tex]C=2\pi r\\ = 2*\pi *3\\=6\pi[/tex]

Since [tex]\pi[/tex] is approximately [tex]3.1415[/tex], [tex]6\pi =6*3.1415=18.849[/tex], which rounds to [tex]18.85[/tex]. Therefore, the circumference of the circle is [tex]6\pi[/tex], or approximately [tex]18.85[/tex] units. Hope this helps!
