Question

Find θ (in radians) for anangle having an arc length of23 and a radius of 15,0 = radians

Answer 1

ANSWER

θ = 23/15 radians

EXPLANATION

The arc length, s, of an angle given in radians and for a radius r is,

$s=\theta r$

Solve for θ,

$\theta=\frac{s}{r}$

In this case, s = 23 and r = 15,

$\theta=\frac{23}{15}rad$

Hence, the angle is 23/15 radians.
