Kwa mazoezi yafuatayo, kubadilisha hatua za angle kwa digrii.

1. $$\frac{\pi}{4}$$

2. $$-\frac{5 \pi}{3}$$

3. $$-210^{\circ}$$

4. $$180^{\circ}$$

5. Kupata urefu wa arc katika mduara wa Radius 7 mita subtended na angle ya kati ya$$85^{\circ}$$.

6. Pata eneo la sekta ya mduara na kipenyo cha futi 32 na angle ya$$\frac{3 \pi}{5}$$ radians.

Kwa mazoezi yafuatayo, pata angle kati$$0^{\circ}$$ na$$360^{\circ}$$ hiyo ni coterminal na angle iliyotolewa.

7. $$420^{\circ}$$

8. $$-80^{\circ}$$

Kwa mazoezi yafuatayo, pata angle kati ya 0 na$$2 \pi$$ katika radians ambayo ni coterminal na angle iliyotolewa.

9. $$-\frac{20 \pi}{11}$$

10. $$\frac{14 \pi}{5}$$

Kwa mazoezi yafuatayo, futa angle iliyotolewa katika nafasi ya kawaida kwenye ndege ya Cartesian.

11. $$-210^{\circ}$$

12. $$75^{\circ}$$

13. $$\frac{5 \pi}{4}$$

14. $$-\frac{\pi}{3}$$

15. Pata kasi ya mstari wa nukta kwenye ikweta ya dunia ikiwa dunia ina radius ya maili 3,960 na dunia inazunguka kwenye mhimili wake kila masaa 24. Express jibu katika maili kwa saa. Pande zote hadi karibu na mia moja.

16. Gurudumu la gari lenye kipenyo cha inchi 18 huzunguka kwa kiwango cha mapinduzi 10 kwa pili. Kasi ya gari kwa maili kwa saa ni nini? Pande zote hadi karibu na mia moja.
