$\dfrac{\pi^2}{180}$ radians
RECALL: To convert an angle measure from degrees to radians, you multiply $\dfrac{\pi}{180^o}$ to the given measure in degrees. Converting the given angle in degree measure to radians gives: $=\pi^o \cdot \frac{\pi}{180^o}=\dfrac{\pi^2}{180}$ Thus, the exact radian measure of the given angle is $\dfrac{\pi^2}{180}$ radians.
