I.  Circumference, Area, Volume

  1. Circumference:      C = 3.14  x  Diameter

  2. Perimeter:              P = (2  x  Length)  +  (2  x  Width)

  3. Area: 
    Rectangle                A = Length  x  Width
    Circle                      A = 0.785  x  Diameter  x  Diameter
    Triangle                   A = 1/2  x  Base  x  Height

  4. Volume: 
    Rectangle         V = Length  x  Width  x  Depth
    Circular            V = 0.785  x  Diameter  x  Diameter  x  Depth
    Cone                V = 1/3  x  0.785  x  Diameter  x  Diameter  x  Height
    Sphere              V = 0.524  x  Diameter  x  Diameter  x  Diameter
     

II.  Time:

 

Hours = Days  x  24 Hours/Day
