Answer:


\pi radian

Explanation:

We know that angle for a full circle is 2
\pi

In the given figure shape is semicircle

hence,

angle for semicircle will be half of angle of full circle

thus, angle for given figure = half of angle for a full circle = 1/2 * 2
\pi =
\pi

Thus, answer is
\pi radian

alternatively, we also know that angle for a straight line is 180 degrees

and 180 degrees is same as
\pi radian.
