Incorrect. In this circle, $\displaystyle{r}={3}\usepackage{cmbright}\Huge\$ feet. The arc determined by $\displaystyle\angle{X}{O}{Y}\usepackage{cmbright}\Huge\$ has length $\displaystyle{s}={6}\usepackage{cmbright}\Huge\$ feet. Substitute these lengths into the formula: $\displaystyle\theta=\frac{{s}}{{r}}\usepackage{cmbright}\Huge\$
