Suppose you were to bend two whole sheets of paper to form two cylinders (a tall, skinny one and a short, wide one). The volume of a cylinder can be calculated using the formula or .

  1. Do the two cylinders have the same volume? Justify your answer.

    Calculate the volume of both cylinders and compare.

    Remember, for cylinders:
    V = πr2h
    C = 2πr
    Where V is volume, r is radius, h is height, and C is circumference.

    For the tall cylinder:

  2. Is the result different if you start with -by- paper?

    See part (a).
