what if you divide circumference by diameter and don't get pi ? What does that mean about the circle (because today i got numbers that were exactly over pi and some were even under)?

  • Happy π day to all mathematicians -

    Today, March 14, at 1:59 was a very special time

    Joke: ??

    A mathematician, a physicist, and an engineer are all given identical
    rubber balls and told to find the volume. They are given anything they
    want to measure it, and have all the time they need.
    The mathematician
    pulls out a measuring tape and records the circumference. He then
    divides by two times pi to get the radius, cubes that, multiplies by pi
    again, and then multiplies by four-thirds and thereby calculates the

    The physicist gets a bucket of water, places 1.00000 gallons of
    water in the bucket, drops in the ball, and measures the displacement
    to six significant figures.

    And the engineer? He writes down the serial
    number of the ball, and looks it up.
