## If you have the time, Circumference

### Circumference is the perimeter of a circle.The circumference of a circle can be calculated using radius or diameter: C = 2 * π * r or C = π * d 2

## Which French philosopher and mathematician is famous for his creation of the Cartesian coordinate system, still used today in algebra and geometry?

### René Descartes (1596-1650)You may remember the Cartesian coordinate system as a plot of X, Y on a two-dimensional axis.  This changed the way mathematicians were able to describe functions (correlational relationships). 5

## Area

### Area is the measure of space on a surface. It is measured in units squared.Common area equations include: Circle: A = π r^2 Triangle: A = 1/2 b * h Rectangle: A = s1 * s2 Parallelogram: A = b * h 16
