I am also the author of The Joy of Game Theory: An Introduction to Strategic Thinking, and several other books which are available on Amazon. I run the MindYourDecisions channel on YouTube, which has over 1 million subscribers and 200 million views. Videos on YouTube, problem from the 2017 GCSE exam We then add 2 radius lengths to get the entire side length, which is then r(2 + √3). If we connect the centers of the 3 circles, we get an equilateral triangle with a side length of 2 r. The tricky part is the vertical distance between the centers of the circles.
The horizontal distance is equal to 4 radius lengths, or 4 r. We can solve for the side lengths by drawing radii of the circles. (Pretty much all posts are transcribed quickly after I make the videos for them–please let me know if there are any typos/errors and I will correct them, thanks).

Since 2007, I have devoted my life to sharing the joy of game theory and mathematics. Rectangle Area From 3 Identical Circles – Solving Hard GCSE Problem The problem is adapted from one of the hardest GCSE exam problems (a test given in the UK). If each circle has a radius of r, what is the area of the rectangle in terms of r? (the top two circles are tangent to two sides of the rectangle the bottom circle is tangent to one side of the rectangle each circle is tangent to the other two circles) (rated 4.2/5 stars on 22 reviews) Kindle UnlimitedĪ rectangle contains 3 identical circles as shown in the diagram.

This column has been revised to reflect that the arrangement of spheres in Exercise 2 is a "simple cubic" packing, not a "body-centered cubic" packing. It is interesting to note that this is not the densest possible packing of octagons in the plane. How does that compare to the area of the hexagon? A hexagon of side length s is really six equilateral triangles of side length s, each with area $latex \frac$ ≈ 0.8284
