Answer:
arc\ length =13.19cm

Explanation:

You need to use the following formula:


arc\ length=r\theta

Where "r" is the radius and
\theta is is the central angle of the arc in radians.

Assuming that that the angle
(3\pi )/(5) is the central angle of the arc, and knowing that the radius is 7 centimeters, you can substitute values into the formula.

Therefore, you get:


arc\ length=r\theta\\\\arc\ length= (7cm)((3\pi)/(5))}\\\\arc\ length =13.19cm
