Work Step by Step

RECALL: $\omega=\dfrac{\theta}{t}$ Substitute the given values into the given formula above to obtain: $\omega=\dfrac{\theta}{t} \\9\text{ radians per sec}= \dfrac{\theta}{12\text{ sec}}$ Cross-multiply to obtain: \begin{array}{ccc} &\theta&=&(9 \text{ radians per sec}) \cdot (12\text{ sec}) \\&\theta &=&108 \text{ radians}\end{array}
