Answer 1

A. 10π
B. 10π/3
C. 10π/6
D. 10π/9

Answer 2

What is the question ? You have to find what?

Answer 3

\[arc length = r*\Theta\]

Answer 4

Where theta is in radians. To convert degrees to radians, multiply by pi/180.

Answer 5

1. convert 40 degrees to radians. 40 x pi/180 = 2pi/9

2. multiply by radius, 5. 2pi/9 x 5 = 10pi/9

3. select answer choice D
