Answer:
3.49 radians
Step-by-step explanation:
The arc length formula is s = rФ, where r is the radius and Ф is the central angle. We know s and r and need to calculate Ф.
From s = rФ we get Ф = central angle = s/r
Here, that central angle Ф is (31.4 cm) / 9 cm = 3.49 radians
47-25= 22
22 divided by 47 =0.468 aka 47% increase
Where's the figure cause Idk
Answer: angle 4 and angle 5
Complementary angles, if added together, make a right angle or 90* angle
