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.
