Find the measure (in radians) of a central angle, $\theta$, that intercepts an arc on a circle with radius 28 ft and arc length 21 ft.
A) 1.3 radians
B) 0.8 radians
C) 588.0 radians
D) 7 radians

Question

Quizplus · Accepted Answer

The measure of a central angle in radians is given by the formula $\theta = \frac{s}{r}$, where $s$ is the arc length and $r$ is the radius. Here, $\theta = \frac{21}{28} = 0.75$ radians, which is closest to 0.8 radians.
