Perimeter of rectangle = 2L + 2W | Area of rectangle = L W |
Perimeter of circle = 2 π r | Area of triangle = 1/2 b h |
Pythagorean theorem: a2 + b2 = c2 | Area of circle = π r2 |
Surface area of box = 2 L W + 2 L H + 2 H W | Volume of box = L W H |
Surface area of cylinder = π r2 + 2 π r h | Volume of cylinder = π r2 h |
Surface area of sphere = 4 π r2 | Volume of sphere = 4/3 π r3 |
