The goal of this GeoGebra Augmented Reality modeling challenge, is to author 2 surface equations (with domain restrictions) in order to design a wiffle ball (as seen in this screencast). [br][br][b]Modeling Clues:[/b][br][br]1) The ball itself is a sphere of radius 5 centered at (0,0,0). [br][br]2) The projection of the small top hole onto the plane z = 0 is a circle with radius = [math]\frac{\sqrt{2}}{2}[/math]. [br][br]3) The projections of each of the 6 equally-spaced openings onto the plane z = 0 are ellipses whose centers are 3.8 units away from (0,0,0). Each ellipse has major axis length [math]\frac{4\sqrt{5}}{5}[/math] & eccentricity = [math]\frac{\sqrt{3}}{2}[/math]. [br][br]**As an added challenge, try to construct the [b][color=#1e84cc]blue hemisphere[/color][/b] using only 3 domain restrictions.
