Circular Measure

The correct method to convert  $56^{\degree}$  to radian is.........

•  $56+\frac{180}{\pi}$  

•  $56\times\frac{180}{\pi}$  

•  $56\times\frac{\pi}{180}$  

•  $56+\frac{\pi}{180}$  

The correct way to conver 5.6 rad to degree is......

• $5.6\times\frac{180}{\pi}$

• $5.6\times\frac{\pi}{180}$

• $5.6\div\frac{180}{\pi}$

• $5.6\div\frac{\pi}{180}$
