CIRCLE
Area = Square of Diameter x .7854 or Square of Radius x 3.1416
Circumference = Diameter x 3.1416
Diameter = Circumference x .3183
Circumference = Diameter x 3.1416
Diameter = Circumference x .3183
Doubling diameter increases area four times; tripling diameter increases area nine times, etc.
SQUARE
Area = Square of Side
Diagonal = Side x 1.4142
Side = Diagonal x .7071
Diagonal = Side x 1.4142
Side = Diagonal x .7071
SQUARE INSCRIBED IN CIRCLE
Side of Square = Diameter of Circle x .7071 or Circumference of Circle x .2251
Diameter of Circle = Side of Square x 1.4142
Circumference of Circle = Side of Square x 4.4429
Diameter of Circle = Side of Square x 1.4142
Circumference of Circle = Side of Square x 4.4429
SQUARE AND CIRCLE WITH EQUAL AREA
Side of Square = Diameter of Circle x .8862
Diameter of Circle = Side of Square 1.128
Circumference of Circle = side of Square x 3.545
Diameter of Circle = Side of Square 1.128
Circumference of Circle = side of Square x 3.545
RECTANGLE
Area = Length x Width
Diagonal = Square root of sum of squares of Width and Length
Diagonal = Square root of sum of squares of Width and Length
TRIANGLE
Area = Base x 1/2 of Perpendicular Height
HEXAGON (Equal sides and angles)
Area = Square of Distance across Flats x .866 or Square of Side x 2.598
Side = 1/2 of Diagonal or Distance across Flats x .577
Diagonal = Distance across Flats x 1.155 or Side x 2
Side = 1/2 of Diagonal or Distance across Flats x .577
Diagonal = Distance across Flats x 1.155 or Side x 2
OCTAGON (Equal sides and angles)
Area = Square of Distance across Flats x .828 or Square of Side x 4.828
Side = Diagonal x .383 or Distance across Flats x 4.14
Diagonal = Distance across Flats x 1.082 or Side x 2.613
Side = Diagonal x .383 or Distance across Flats x 4.14
Diagonal = Distance across Flats x 1.082 or Side x 2.613
SPHERE
Area of Surface = Square of Diameter x 3.1416
Volume = Cube of Diameter x .5236
Volume = Cube of Diameter x .5236
CUBE
Area of Surface = Square of Side x 6
Volume = Cube of Side
Diagonal = Side x 1.732
Volume = Cube of Side
Diagonal = Side x 1.732
CYLINDER
Area of curved Surface - Diameter x Length 3.1416
Volume = Square of Diameter x Length x .785
Volume = Square of Diameter x Length x .785
CONE
Area of Curved Surface = Diameter of Base x Slant Height x 1.5708
Volume = Diameter of Base Squared x Perpendicular Height x .2618 or Area of Base x 1/3 Perpendicular Height
Volume = Diameter of Base Squared x Perpendicular Height x .2618 or Area of Base x 1/3 Perpendicular Height
PYRAMID
Lateral Surface Area = (not incl. base) = Perimeter of Base x 1/2 Slant Height
Volume = Area of Base x 1/3 Perpendicular Height
Volume = Area of Base x 1/3 Perpendicular Height
