Here is a ‘circle’ made out of Lego. It’s not very circular!
What questions might a mathematician ask?
![An approximation to a circle made from red and yellow 2 by 2 lego bricks. The pattern has mirror symmetry horizontally and vertically. There are ten rows of bricks, with 2, 6, 8, 8 and 10 bricks in the first five rows and then descending 10, 8, 8, 6, 2. The boundary of the shape is yellow and the middle is red.](https://alisonkiddle.co.uk/wp-content/uploads/2023/08/Lego7-1024x1024.jpg)
What is the ‘radius’ of this circle? What is the area?
How could you make a better circle out of Lego?
