Given the radius of the circle = 4 cm.

The arc is intercepted by a central angle of 2.5 radians.

So,

$\begin{gathered} r=4\operatorname{cm} \\ \theta=2.5\text{ rad.} \end{gathered}$

The length of the arc is given by the formula:

$A=\theta\cdot r$

Substitute with the given values;

$A=2.5\cdot4=10\operatorname{cm}$

So, the answer will be option C. 10 cm
