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.
