The equation of the circumference of a circle is $\displaystyle{C}={2}\pi{r}\usepackage{cmbright}\Huge\$ , where $\displaystyle{r}\usepackage{cmbright}\Huge\$ is the radius of the circle. Compute the circumference of a circle whose diameter is $\displaystyle{3.8}\usepackage{cmbright}\Huge\$ cm. Use the approximation $\displaystyle\pi={3.14}\usepackage{cmbright}\Huge\$ and round your answer to one decimal place.
