Simon has made a table of how to calculate the areas of various shapes. The ellipse one made him especially happy:
πr x h/2
Which one is r, I asked, and which one is h? Is h the longer line? – It doesn’t matter, Mom, because you divide them both by two in the end, Simon said. That’s funny how he sees those things earlier than I.
And in a circle, the radius and the hight divided by two is the same! – he added in English.
Earlier the same day:
Neva shouts: Mom, the film was first 2D and then all of a sudden 3D!
Simon: No, it was first πr² and then it became 4πr²!
