Question

an intercepted arc has a length of 19 yards. If the radius is 4 yards, find the measure of the central angle in radians and degrees.

Answer 1

`s=r\theta\\\theta=s/r\\\theta=19/4\\\theta=4.75`

Explanation:

There is a formula that relates the arc length of a circle of radius, r, to the central angle,
`\theta` in radians.

`s=r\theta`
