Two squares of area D and J share a vertex while the circle passes through four other vertices. What is the area of the latter in terms of D and J?
Scroll down for a solution to this problem.
Solution
The circle area is (D+J)π/2.

Poem
The circle is full
Full of squares
Which hold each other together
Arcs and angles
That support the vaults
Of cathedrals
In flamboyant style
Soaring to the sky
Geometrical look
For an optical illusion
Mystical figures
Here we go
Trying gently
Squaring the circle
