Answer:

≈119.3

Step-by-step explanation:

The area for circumference is as follows:

[tex]C = 2\pi r\\or\\C = d\pi[/tex]

The above equations mean the same thing, because the diameter is just 2 times the radius.

Anyhow, we insert this value into the equation...

[tex]C = 2\pi(19)\\C = 38(3.14)\\C = 119.32\\[/tex]

This rounds to:

≈119.3
