Answer:

First drawing - answer is:  D: DG, FG and DE

Second drawing - answer is:  π (pi)

Third drawing - answer is:  70° ( If you mean on measure of central angle which is corresponing to the arc CB)

Fourth drawing - answer is: y=55° ( If you mean that the value of angle ∠AOB=70° )

Step-by-step explanation:

For the second drawing

arc AB = (r · π / 180) · α = (3 · π/180) · 60 = (180 · π) / 180 = π

For the third drawing

∠CAB is peripheral angle of the central angle ∠CFB.

∠CFB= 2·∠CAB= 2· 35° = 70°

Good luck!!!
