*percent error: amount of error (find the difference) divided by the actual amount.
*Circumference = pi times the diameter or 2 times the radius times pi.
*Area of circle = pi times the radius squared
*Types of graphs and when to use them:
Bar Graph - categories
Box plot - lots of data, to show variation
Cirlce Graph - %
Histogram - intervals, like 1-5 and 6-10
Line Graph - changes over time
Line Plot - number line
