We all know that to cut a (circular) pie,
1 cut gives us at most 2 pieces,
2 cuts give us at most 4 pieces,
3 cuts give us at most 7 pieces.
It is clear for 1 cut and 2 cuts, how we can get these pieces to be the same size.
Can we cut a circular pie into 7 equal pieces with 3 cuts?
If no, why not?
If yes, can we cut a circular pie into 11 equal pieces with 4 cuts?
This thought occurred to me as I was adding an image to Vatsalya's Problem.
