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.

The length of an arc is the distance between the endpoints of the arc.

The central angle is: or

The given parameters are:

--- length of the arc

-- radius of the circle

The length of an arc is calculated as:

Divide both sides by r

Substitute known values

Convert to degrees as follows:

Hence, the central angle is: or

the simplified form is

step-by-step explanation:

we want to simplify the expression,

let us change the middle bar to a normal division sign to obtain,

we multiply the first fraction by the reciprocal of the second fraction to obtain,

we factor to obtain,

we cancel the common factors to get,

we simplify to get,

the correct answer is b
