I don't know how to solve this problem! I just don't understand it. I know they want me to find the radius but I just don't how. Here's the word problem and the question I'm stuck on.

My mom made a round cake with a 10 inch radius. She cut the cake into 16 equal slices. When 1 slice was left, my sister and I both wanted it, so we agreed to cut it in half, but I like the icing more than she does, so we decided to cut it the "other way." In other words, the two pieces would not be symmetrical. The inside piece would contain less icing, and the outer piece would contain the icing.

5. What is the radius of a half-piece when it is cut as shown in the picture? (ie, where do I need to cut to make two equal halves out of a piece?)
