$13\frac{1}{3}^{\circ}$, $\frac{2\pi}{27}$ radians
Since a complete circle represents $360^{\circ}$, the measure of each central angle can be found by dividing $360^{\circ}$ by the number of spokes i.e. $27$: Each central angle=$\frac{360^{\circ}}{27}=13\frac{1}{3}^{\circ}$ Since a complete circle represents $2\pi$ radians, the measure of each central angle can be found by dividing $2\pi$ radians by the number of spokes i.e. $27$: Each central angle=$\frac{2\pi}{27}$ radians
