Радианные меры углов

1. A) $$300^{\circ} = \frac{300}{180} \pi = \frac{5}{3} \pi \approx 1.67\pi$$
2. Б) $$225^{\circ} = \frac{225}{180} \pi = \frac{5}{4} \pi \approx 1.25\pi$$
3. В) $$270^{\circ} = \frac{270}{180} \pi = \frac{3}{2} \pi = 1.5\pi$$
4. Г) $$400^{\circ} = \frac{400}{180} \pi = \frac{20}{9} \pi \approx 2.22\pi$$
5. Д) $$450^{\circ} = \frac{450}{180} \pi = \frac{5}{2} \pi = 2.5\pi$$
6. E) $$800^{\circ} = \frac{800}{180} \pi = \frac{40}{9} \pi \approx 4.44\pi$$
