#### Answer:

Period $T = \frac{2 \pi}{\omega}$

#### Explanation:

Period $T = \frac{2 \pi}{\omega}$, where $\omega$ is angular speed

this is a direct analogue to the linear idea that

$\text{time" = "Distance"/"Speed}$

.....because $2 \pi$ is a full revolution, the "distance", and it is done at angular speed $\omega$.
