<h3>
Answer:</h3>
A.) 3 pi cm
<h3>
Step-by-step explanation:</h3>
The formula for arc length (s) as a function of radius (r) and central angle (θ) in radians is ...
... s = rθ
Here, you have r=9 cm and θ=(60°/180°)π = π/3 radians, so the arc length is ...
... s = (9 cm)·π/3 = 3π cm
Answer:
490
Step-by-step explanation:
d(x)=700-7(30)
7x 30=210
700-210=490
therefore,
r(x)=490
Answer: 16 questions
