Square Pegs in Round Holes
As the kids are taking down their tent they strike up a philosophical conversation about square pegs in round holes and thence round pegs in square holes. They ask their parents the following question:
Which fits better: a square peg in a round hole or a round peg in a square hole?
Can you help the parents solve this problem? Consider a square inscribed within a circle and circle inscribed within a square as illustrated below. In each case, find the area of the shaded section as a percentage of the whole.
