Recall that the total angle measure of a full circle in radians is given by the formula \(2\pi\) radians.
Understand that half of a circle corresponds to half of the total angle measure of the full circle.
To find the radians in half of a circle, divide the total radians of the full circle by 2, which gives \(\frac{2\pi}{2}\).
Simplify the expression \(\frac{2\pi}{2}\) to get \(\pi\) radians.
Therefore, half of a circle measures \(\pi\) radians.
