⁴/₃π radian
<h3>Further explanation</h3>Given:
Arc CD is of the circumference of a circle.
We will measure the central angle of the circle in radians.
Step-1: measure the central angle (θ) in degrees
The full angle of a circle is 360°, thus
We get the degree measure of the middle angle, i.e.,
Step-2: convert degrees to radians
Because , then
Cross out 240° and 180° because they are equally divided by 60°.
Hence, the radian measure of the central angle is
- - - - - - -
Quick Steps
The full angle of a circle is 2π radians.
Hence, the radian measure of the central angle is
One radian represents the measure of a central angle of a circle that intercepts an arc whose length equals a radius of the circle.
