Marni loves pancakes and likes to eat them in a tall stack. Assume that she always makes pancakes with a thickness of inch.

  1. Last Saturday, Marni decided to make square pancakes. If the largest pancake had an edge of inches and each pancake had an edge inch shorter than the one below it, find the volume of pancakes Marni ate last Saturday.

    Volume (Area of Base)(Thickness)

    The area of the base of each pancake is the edge squared.


  2. Next Sunday, Marni will make circular pancakes. This time, each pancake will have a diameter inch smaller than the one below it and the smallest pancake will have a radius of inches. How much volume is she planning to eat?
