If pi is 3.141..., can a circle truly be separated into 4 equal parts?

Yes, a circle can be separated into 4 equal parts.  The parts will 
each have area equal to one fourth of the circle's area, so if the 
circle has radius one, each part will have area pi/4=.785...  

The fact that pi is not an integer means that the area is not an 
integer, but it doesn't mean that we can't divide the circle into 
equal parts.
