ok so the problem wants me to find the area of the circle with center E. it was pretty easy to figure out that the diameter of the small circle was 6. once i figure out the diameter i can use that relationship to say that the area of the circle with center A and center C is 36pi. but this is where im stuck. im not sure how im supposed to use these relationships to figure out the area of the circle with center E. any thoughts or help would be greatly appreciated.
