Question

The radius of a circle is 10 meters. What is the angle measure of an arc 3 meters long?
{=37 m
=10 m
Give the exact answer in simplest form

Answer 1

Answer:

Ф = 0.3 radians

Step-by-step explanation:

The arc length formula is s = rФ.  Solving for the angle measure Ф, we get:

Ф = s/r

and so with r = 10 m and s = 3 m, we get Ф = 3 m / 10 m = Ф = 0.3 radians
