Converting degrees and radians worksheets Grade 11

How to do it

180° = π radians. Degrees to radians: multiply by π/180. Radians to degrees: multiply by 180/π.

Example problems

1. $\dfrac{5\pi }{6}\quad \text{in degrees} =$$150^{\circ}$Show answer
2. $\dfrac{8\pi }{3}\quad \text{in degrees} =$$480^{\circ}$Show answer
3. $570^{\circ}\quad \text{in radians} =$$\dfrac{19\pi }{6}$Show answer
4. $600^{\circ}\quad \text{in radians} =$$\dfrac{10\pi }{3}$Show answer
