Circle and Rhombus - Dec. 16-20, 1996

Next Problem || Previous Problem || Contents || All Problems || Search POWs

I found this problem in a "GRE preparation guide." GRE stands for "Graduate Record Examination," a test sort of like the SAT that people take if they want to go to graduate school. So this is a question being asked of people who have graduated from college and are planning to continue their education. I figured that made it a decent challenge for you!

In the picture below, we have a circle and a rhombus. BC is 6, AE is 4, <DAE is 45 degrees, and AD is a diameter of the circle. How far is it around the perimeter of the whole figure, that is from C->D->F->A->G->E->B->C?

Remember, simple numerical answers won't be accepted. You need to explain how you figured it out.
