4. The arc length of a circle with radius 5 and central angle 2 radians is: \( \begin{array}{ll}0 & \text { a) } 5 \\ \text { b) } & \text { b) }\end{array} \)

Step-by-step Solution
The arc length \( L \) of a circle can be calculated using the formula:
\[
L = r \theta
\]
where \( r \) is the radius of the circle and \( \theta \) is the central angle in radians.
Given:
- Radius \( r = 5 \)
- Central angle \( \theta = 2 \) radians
Substituting the values into the formula:
\[
L = 5 \times 2 = 10
\]
Therefore, the arc length is \( 10 \).
Since the options provided are incomplete, the correct answer is \( 10 \).
Quick Answer
The arc length is 10.
