Given n, the maximum volume occurs when r and h are integers.  Enlargementim Enlargement inquiry Scale factorsim Scale factors inquiry The surface area and volume of cube B are twice the surface area and volume of cube A.      Reflections and coordinatesim  If point (a,b) is reflected in the line y = x, then the image will be at (b,a).      Combined transformations im If you reflect a shape twice in two different lines of reflection, then you can map the object onto the image with one transformation.    Pythagoras' Theorem and trigonometryim Right-angled triangles inquiry Four scalene triangles
