circle has 2 sides, inside and outside.
btw pics would be great 
has to be one shape that fits all 3 holes exactly. (no spaces)
apparently this question is easier to answer if you are a woman...something about men not having the spatial dimension awareness to be able to visualize it.

Top view of the cylinder. O is at the center. ABCD is the upper circle, and WXYZ are located directly underneath these. The side view of the cylinder appears as a square, because the diameter AC is equal to the height AW. Now, imagine truncating the solid by planes BDW and BDY, leaving the triangle shown in the lower right. The solid that remains will pass through and plug a circle (its base WXYZ is a circle), a square (using square DBXZ), and a triangle (BWY) whose height is equal to its base.
What single 3d shape fits into each of a circle, square and triangle holes ?
(touches all the sides on each)
A sphere (at the widest point) or a cylinder, not shown the circle for obvious reasons.

cant see pic (at work) ill check at home but that sounds about right, thanks!

I thought it was women who lacked this, hence why they suck at reading maps?

Good work
"what fits into a cirlce, square and triangle". NOT "what fits into a sphere, a cube and a pyramid!
and yes, it's men that have better spacial awareness - you know, from all the hunting in days of yesteryear.
Erm, a cube is made up of 6 square sides, a pyramid 4 triangles (and the base, but that's irrelevent here). Just seemed easier to visulise in 3d.
Aha, busted!
Fixed.
