Question

Alison is jogging on a circular track that has a radius of 140ft. The runs along the track from point R to point N (Major arc), a distance of 230ft. Find to the nearest degree the measure of minor arc RN

Answer 1

Answer:

The value of angle of arc RN $\theta = 94.17$ °

Step-by-step explanation:

Radius of the arc = 140 ft

Length of the arc = 230 ft

The angle of arc is given by the formula

$\theta = \frac{arc length}{radius }$

$\theta = \frac{230}{140}$

$\theta = 1.642 \ radian$

$\theta = 1.642 \frac{180}{\pi}$

$\theta = 94.17$ °

This is the value of angle of arc RN.
