Arc CD is 2/3 of the circumference of a circle. What is the radian measure of the central angle? frac 2 ? 3 radians frac 3 ? 4 radians frac. Further explanation. Given: Arc CD is of the circumference of a circle. We will measure the central angle of the circle in radians. Cross out 240° and 180°. Arc CD is 1/4 of the circumference of a circle. What is the radian measure of the central angle? pi/2 radians.Arc CD is 2/3 of the circumference of a circle. What is the radian measure of the central angle? 2(pie)/3 radians 3(pie)/4 radians 4(pie)/3. Get the detailed answer: Arc CD is 2/3 of the circumference of a circle. What is the radian measure of the central angle?
