Question

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

Answer 1

`(\pi^(c) )/(3)`

Explanation:

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

`l = ( \theta)/(2\pi) * 2\pi r \\ \\ \pi = ( \theta)/(2\pi) * 2\pi * 3 \\ \\ 3 \theta = \pi^(c) \\ \\ \theta = (\pi^(c) )/(3) \\`
