Question 604277: Find the degree measure, to the nearest tenth, of the central angle whose intercepted arc measures 20 inches in a circle whose radius is 12 inches.
I have done problems where you find the central andgle, radius, or length of the arc and understand...but this question is confusing me. Thanks for your help!
