## Trigonometry (10th Edition)

Refer to the step-by-step part below for the solution. $3\pi = 540^o$
An angle in radian measure can be converted to degree measure by multiplying $\dfrac{180^o}{\pi}$. Example: $\require{cancel}3\pi \\= 3\pi \cdot \dfrac{180^o}{\pi} \\= 3\cancel{\pi} \cdot \dfrac{180^o}{\cancel{\pi}} \\=3(180^o) \\=540^o$
