The statement is true.
\Because, the length of an arc of the circle is
, where
is radius of the circle and
is central angle measured in radians.
From the given data, the central angle
is in degrees.
So, convert the angle
into radian measure.
Two radians equals to 360 degrees, i.e,
.

Thus,
radians.
Therefore, the length of an arc of the circle is
.
The statement is true.
