I have a solution; how do I share it?

The image is a "shark fin" The area of the shaded area (the shark fin) is ¼ of the black circle with radius 56 minus ½ of the white circle with radius 25 gives the area of the "shark fin" : 392π

@Calvin Lin No, I did not post it as a problem. It was a problem and I noticed there were no solutions as yet. So I tried to give mine. Ans is 392π square units. But I'm not sure if I did it correctly. Can you let me know? How do I find this problem again? I do not know the title; I called it "fin" because it reminded me of a shark fin.
