Stuff :)

Look at the above image. If we split up the ellipse thingy into two and put them in the regions colored blue and red, then, we get the following image -

As you can see now, there is a right-isosceles triangle in the middle of the quarter-circle. It has a base and height of 44, so its area is 4×4×12=84 \times 4 \times \dfrac{1}{2} = 8.

The quarter-circle has an area of πr24=π424=4π\dfrac{\pi r^{2}}{4} = \dfrac{\pi 4^{2}}{4} = 4 \pi

A small GIF showing all the stuff I said above, if it was to hard to understand -

Thus, the orange area is

4π8\boxed{4 \pi - 8}


An alternative solution for those who think the above is felony (lol)

As proved in the preface, the area of the regions shaded blue in the above image have an area of 4π4 - \pi each.

Now, the remaining white regions are the regions shaded red in the image below. These have radii of length 22 each, so they're areas are π\pi each.

So, the total white area is π+π+4π+4π=8\pi + \pi + 4 - \pi + 4 - \pi = 8. Now, the orange area is equal to the area of the main quarter-circle minus the white regions area.

We have already calculated that the area of the main to be 4π4 \pi.

Thus, again the answer is 4π8\boxed{4\pi - 8}

This discussion board is a place to discuss our Daily Challenges and the math and science related to those challenges. Explanations are more than just a solution — they should explain the steps and thinking strategies that you used to obtain the solution. Comments should further the discussion of math and science.

When posting on Brilliant:

  • Use the emojis to react to an explanation, whether you're congratulating a job well done , or just really confused .
  • Ask specific questions about the challenge or the steps in somebody's explanation. Well-posed questions can add a lot to the discussion, but posting "I don't understand!" doesn't help anyone.
  • Try to contribute something new to the discussion, whether it is an extension, generalization or other idea related to the challenge.
  • Stay on topic — we're all here to learn more about math and science, not to hear about your favorite get-rich-quick scheme or current world events.
