Answer:
D
Step-by-step explanation:
We need the formula for arc length (in radians) to solve this problem. The formula is:

Where
s is the arc length
r is the radius of the circle
 is the intercepted angle
 is the intercepted angle
In this diagram, we can see that   is beign intercepted by the big arc with measure 20 cm. So arc length, s, is 20
  is beign intercepted by the big arc with measure 20 cm. So arc length, s, is 20
Also, if we look, we see that the radius is 5 cm, so r = 5
Now, we substitute into formula and find  :
:

This is given in radians, so  is 4 radians
 is 4 radians
D is the correct answer choice.
