Question

A pie can be cut into more than seven pieces by making four diameter cuts.

True or False?

Answer 1

true
a diameter cut goes through the middle of the pie


if we do one cut, we get 2 pices
if we do another one, perpendicular to first, we get 4 pieces
another cut (3rd), with a line that is an angle bisector of the other 2 lines, we get 6 pieces
4th, with a line perpendicular to the 3rd, we get 8 pices

8>7 so true

Answer 2

I'm pretty sure it's true
