Homework:
Memorize the following formulas:
Area of parallelogram: Area = base x height
Area of Triangle: Area = (base x height) / 2
Area of Circle: Area = radius x radius x pi (radious squared times pi)
Circumference of Circle: C = diameter * pi or C = 2 x radius x pi
You must know them perfectly, otherwise you may have to write them a couple hundred times!!!
