Answer:

The angle has a measure of
(5\pi)/(6) radians.

Explanation:

According to the statement, an angle centered at the center of the circle covers an arc of
(25\pi)/(6) units, the arc is a portion of the circunference. We include a figure representing the circle below.

Where:


R - Radius, measured in units.


s - Arc, measured in units.


\alpha - Angle of the arc, measured in radians.

From Geometry, we can calculate the length of the arc by means of this equation:


s = \alpha\cdot R (1)

If we know that
R = 5 and
s = (25\pi)/(6), then the angle of the arc is:


\alpha = (s)/(R)


\alpha = ((25\pi)/(6) )/(5)


\alpha = (25\pi)/(30)


\alpha = (5\pi)/(6)\,rad

The angle has a measure of
(5\pi)/(6) radians.
