 Question 601836: Hello, I have difficulty with a question in a test study guide I am working on. It has a figure of a circle with 2 segments parallel to each other. The problem is written below: In the figure above, lines AE and BD are parallel, and line AD is the diameter of the circle. If the length of arc BCD is equal to 4π, then what is the area of the circle? Lines AE and BD are the chords of each segment and between B and D is the arc C. Also there is a line of the diameter of the circle connecting A and D. The angle of EAD is 30 degrees. That is all the information given. I am more interested in the correct formula to use than the answer. So please just show me the method to get the area of the circle using this information. Thank you for your help.
