4-136.

Draw a flag that would generate the same volume no matter if it were rotated about the - or

*-axis. Is there more than one possible shape of flag that meets this requirement? Does your flag have any special property that ensures these equal volumes of rotation?*

What type of symmetry will your flag need to have?
