What is the measure of the central angle of a circle with radius 15 ft that intercepts a 10 ft arc?

Use 3.14 for π .
 

Round the answer to the hundredths place.

We can solve this for  A

 

10  =  radius * 3.14  * ( A / 180)

 

10  =  15 * 3.14  *  (A / 180)     multiply both sides by 180

 

1800  =  15* 3.14  * A      divide both sides by  15* 3.14

 

1800 / [ 15 * 3.14 ]  =  A  ≈  38.22°
