Question

What is the measure (in radians) of central angle 0 in the circle below? Enter an exact expression.

Answer 1

Answer:

$\frac{\pi^{c} }{3}$

Step-by-step explanation:

Measure of the length of an arc of a circle is given as:

$l = \frac{ \theta}{2\pi} \times 2\pi r \\ \\ \pi = \frac{ \theta}{2\pi} \times 2\pi \times 3 \\ \\ 3 \theta = \pi^{c} \\ \\ \theta = \frac{\pi^{c} }{3}$
