Question

A circle has a circumference of 6. It has an arc of length

CO
What is the central angle of the arc, in degrees?
2 of 4 -

Answer 1

Ф = CO/(6 units)

Explanation:

The formula for arc length is s = rФ, where Ф is the central angle. This can be solved for Ф, the central angle:

arc length

Ф = ------------------

radius

If the given arc length is represented by CO, then the central angle is

Ф = CO/(6 units)
